You can install Oracle Linux 7 on x86-64 systems with up to 2048 logical CPUs and 64 TB of memory. The theoretical upper limit is 5120 logical CPUs and 64 TB of memory, but Oracle has not tested this configuration. A minimum of 2 logical CPUs and 1 GB of memory per logical CPU is recommended. Although the minimum disk space required for installation is 1GB, a minimum of 5 GB is recommended.
The following table describes the maximum file size and maximum file system size for the btrfs, ext4, and XFS file systems. File system limitations are affected by kernel versions and features, and by the architecture of the system on which Oracle Linux is installed. The values depicted here are estimates based on the known variables that might affect the maximum theoretical value that can be achieved. The theoretical values might be higher than those depicted here, and the actual achievable values might be lower than the values shown, depending on the hardware and the kernel version that is used.

The limits for the ext4 file system that are described here are higher than recommended and might prove unstable. If you plan to work with systems where you are intend to work towards using higher file system sizes or file sizes, it is recommended that you use either the btrfs or XFS file system.
The maximum supported size for a bootable logical unit number (LUN) is 50 TB. GPT and UEFI support are required for LUNs that are larger than 2 TB.
The maximum size of the address space that is available to each process is 128 TB.
Oracle Linux 7 Update 6 ships with the following kernel packages:
kernel-3.10.0-957.el7
Red Hat Compatible Kernel (RHCK).
kernel-uek-4.14.35-1818.3.3.el7uek
Unbreakable Enterprise Kernel Release 5 (UEK R5), which is the default kernel.
The Oracle Linux release is tested as a bundle, as shipped on the installation media image. When installed from the installation media image, the minimum kernel version supported is the one that is included in the image. Downgrading kernel packages is not supported, unless recommended by Oracle Support.
Note that previous releases of UEK, such as UEK R4, are not included on the installation media image but can be installed from the Oracle Linux yum server or from the Unbreakable Linux Network (ULN).
The kernel source code for the shipped kernel is available after the initial release through a public git source code repository at https://github.com/oracle/linux-uek .
Table of Contents
This section describes new features and changes in Oracle Linux 7 Update 6. For details of the new features and changes in the initial release of Oracle Linux 7, see the Oracle Linux 7 Release Notes .
The following clustering features, bug fixes, and enhancements are included in this update. See the Oracle Linux Administrator's Guide for Release 7 at https://docs.oracle.com/cd/E52668_01/E54669/html/ol7-pacemaker.html for more information on clustering technology and support limitations.
Pacemaker now supports path, mount, and timer systemd unit files.
Although previous releases of Pacemaker supported
service
and
socket
systemd unit file, alternative units would fail. Pacemaker
can now manage
path
,
mount
and
timer
systemd units, as well.
Pacemaker LVM resource agent updates.
New functionality and updates have been applied to the LVM
resource agents for better management of shared storage
across hosts. The new daemon,
lvmlockd
,
has been included to coordinate access to shared storage
by interfacing with an external lock manager to perform
locking on LVM. This daemon is intended to replace
clvmd
. New resource agents have been
implemented to manage the different implementations. An
lvmlockd
resource agent is available to
manage the
lvmlockd
daemon. The new
LVM-activate
resource agent assists
with the handling of LVM activation and deactivation and
can be configured to either work with
clvmd
or with
lvmlockd
, depending on your
implementation. For more information about
lvmlockd
, see the manual for
lvmlockd(8)
.
The
lvm
resource agent has also been
patched to accept the
volume_group_check_only
parameter. This
parameter can be set to limit monitoring to only volume
groups, avoiding timeouts on tagged volumes. This parameter
must not be used with the
LVM-activate
resource agent.
The following file systems features, bug fixes, and enhancements are included in this update.
btrfs: File system deprecated in RHCK. Starting with Oracle Linux 7 Update 4, btrfs is deprecated in RHCK. Note that btrfs is fully supported with UEK R4 and on UEK R5.
pNFS
SCSI layout support in RHCK.
Parallel NFS (pNFS) SCSI layouts are supported when using
RHCK.
The following installation and upgrade features, bug fixes, and enhancements are included in this update:
In-place upgrade from Oracle Linux 6 to Oracle Linux 7. The in-place upgrade tools are updated to support upgrading from Oracle Linux 6 to Oracle Linux 7 by replacing the existing operating system. The provided tools can help to check for potential issues during upgrade and ease upgrade processes. See Section 6.1, “Upgrading from Oracle Linux 6” for more information.
Booting from an iSCSI device that is not configured by using iBFT now
supported.
The installer now includes a new boot option,
inst.nonibftiscsiboot
. This boot option
can be used to install the boot loader onto an iSCSI
device that has not been configured in the iSCSI Boot
Firmware Table (iBFT).
Installing and booting from NVDIMM devices now supported. The installer is now capable of recognizing Nonvolatile Dual Inline Memory Module (NVDIMM) devices when installing or booting NVDIMM devices in sector mode and can be used to reconfigure NVDIMM devices into sector mode during installation.
This update also includes an extension to the kickstart
scripts for the installer, to facilitate new commands for
handling NVDIMM devices. Other updates were applied to
system components, such as
grub2
,
efibootmgr
and
efivar
,
to handle booting from these devices.
The following changes are specific to RHCK. For more information, refer to latest versions of the release notes for Oracle Linux Unbreakable Enterprise Kernel Release 5 in the Unbreakable Enterprise Kernel Documentation library.
Updated
kexec-tools
documents for the Kdump FCoE
target.
The documentation for
kexec-tools
has
been updated to include instructions on using a Fibre
Channel over Ethernet (FCoE) target with Kdump.
NVMe driver updated to version 4.17-rc1. The NVMe driver that ships with RHCK has been updated to version 4.17-rc1. This driver includes several bug fixes and enhancements, including a number of improvements for the use of NVMe over Remote Direct Memory Access (RDMA).
MySQL Community packages are not included on the provided ISO in this release. This change ensures that the ISO size is appropriate for use on typical DVD-ROM media. The MySQL Community 8.0, MySQL Community 5.7, MySQL Community 5.6, and MySQL Community 5.5 packages continue to be available on the Unbreakable Linux Network (ULN) and the Oracle Linux yum server.
You can install MySQL Community packages directly from ULN or
from the Oracle Linux yum server by enabling the appropriate channel or
repository. For example, you would enable the
ol7_MySQL57
repository on the Oracle Linux yum server to
install the MySQL Community 5.7 packages as follows:
# yum-config-manager --enable ol7_MySQL57
The following networking features, bug fixes, and enhancements are included in this update:
ECMP
fib_multipath_hash_policy
support added to the
kernel for IPv4 packets.
RHCK is updated to include support for the Equal-cost
multi-path routing (ECMP) hash policy by using the
sysctl
command with the
fib_multipath_hash_policy
option. When
the value for this option is set to
1
,
the kernel performs an L4 hash (multipath hash on IPv4
packets). When the default value of
0
is set, only an L3 hash is used.
Note that if you enable
fib_multipath_hash_policy
, ICMP error
packets are not hashed according to the inner packet
headers, which is a problem for anycast services, as the
ICMP packet could be delivered to the incorrect host.
Support for hardware time stamping on VLAN interfaces.
Hardware time stamping can be used on VLAN interfaces,
where the hardware and driver module supports this
functionality. This feature allows applications, such as
linuxptp
, to enable hardware time stamping.
IFDOWN_ON_SHUTDOWN
option available in
/etc/sysconfig/network-scripts
.
A new option for use when configuring network interfaces
in
/etc/sysconfig/network-scripts
is
available. You can set the
IFDOWN_ON_SHUTDOWN
option to
no
or to
false
to
prevent a network interface from being taken down when the
network
service is stopped or
restarted.
This option can be useful in preventing mount points that use networked-based file systems, such as NFS, from becoming stale if the network is stopped before the file system is cleanly unmounted.
More detail in
network-scripts
error messages for the
bonding driver.
Error messages that are related to the failure of bonding
driver installation have been made more verbose when using
/etc/sysconfig/network-scripts
to
manage an interface.
The following security features, bug fixes, and enhancements are included in this update:
Clevis support for TPM 2.0.
The Clevis automated encryption framework that can
automatically encrypt or decrypt data or unlock LUKS
volumes, is updated to support the encryption of keys in a
Trusted Platform Module 2.0 (TPM2) chip. Note that this
feature is only available for
x86_64
platform systems.
gnutls
version updated to 3.3.29.
The GNU Transport Layer Security package,
gnutls
, has been upgraded to 3.3.29 to
include numerous bug fixes and enhancements. Notably, DSA
support has been added to
p11tool
,
providing a stricter requirement around DER encoding to
reduce BER rule complexity. In addition, the legacy
HMAC-SHA384
cipher is disabled by
default, and security improvements have been implemented
to counter TLS Cipher Block Chaining (CBC) record padding
attacks.
audit
version updated to 2.8.4.
The Linux Audit system is updated to version 2.8.4 to
provide bug fixes and enhancements. Notable changes
include the addition of a facility to track software
updates and installations by using the
rpm
or
yum
command.
The updated version of
audit
also
includes improvements to remote logging, and an option to
dump internal state to
/var/run/auditd.state
by using the
SIGCONT
signal. Run the
service auditd state
command to trigger
a dump of the internal state and view the output.
Package installation and upgrade using
rpm
can be
tracked by using
audit
events.
The RPM package manager is updated to provide
audit
events so that software package
installation and updates can be tracked by the Linux Audit
system. This update also means that software installation
and upgrades with the
yum
command are
also tracked.
SELinux
extended_socket_class
policy introduced.
The new
extended_socket_class
policy
enables SELinux object classes to support all known
network socket address families. The policy also supports
separate security classes for ICMP and SCTP sockets that
were previously covered in the
rawip_socket
class.
SELinux file permission check for
mmap()
usage.
SELinux can check file permissions on an
mmap()
system call to prohibit memory
mapping for files that require access validation on each
subsequent access. This is a requirement in environments
where files are often relabeled at runtime to reflect
state changes.
The following virtualization features, bug fixes, and enhancements are included in this update:
Paravirtualized clock support.
The paravirtualized
sched_clock()
function is now integrated into RHCK and enabled by
default. The paravirtualized clock is also available in
the UEK release. The addition of this support improves
the performance of Oracle Linux virtual machines that are running
on some hypervisors, such as KVM, which supports this
functionality in the
kvm_clock
driver.
QEMU guest agent diagnostics enhanced.
New QEMU guest agent commands have been added to improve
diagnostic capabilities that are in line with Virtual
Desktop and Server Management daemon requirements. These
improvements include the addition of the following
commands:
qemu-get-host-name
,
qemu-get-users
,
qemu-get-osinfo
,
and
qemu-get-timezone
.
VNC console support for GPU-based mediated devices. GPU-based devices, including NVIDIA vGPU, can now be used for the real-time rendering of a virtual machine's graphical output through a VNC console.
Features that are currently under technology preview when using UEK R4U6 are described in Oracle Linux Release Notes for Unbreakable Enterprise Kernel Release 4 Update 6 .
For RHCK, the following features are currently under technology preview:
Systemd: Importd features for container image imports and exports.
File Systems:
Block and object storage layouts for parallel NFS (pNFS).
DAX (Direct Access) for direct persistent memory mapping from an application. This feature is under technical preview for the ext4 and XFS file systems.
ima-evm-utils
package, which provides
utilities for labeling file systems and verifying the
integrity of the system at run time.
OverlayFS remains in technical preview.
Kernel:
Heterogeneous memory management (HMM).
No-IOMMU mode virtual I/O feature.
Networking:
Cisco VIC InfiniBand kernel driver, which provides similar functionality to RDMA on proprietary Cisco architectures.
nftables
and
libnftnl
network filtering and
classification functionality.
Single-Root I/O virtualization (SR-IOV) in the
qlcnic
driver.
Support for a Cisco proprietary User Space Network
Interface Controller in UCM servers provided in the
libusnic_verbs
driver.
Trusted Network Connect support.
Storage:
Multi-queue I/O scheduling for SCSI
(
scsi-mq
). This functionality is
disabled by default.
Plug-in for the
libStorageMgmt
API
used for storage array management. The
libStorageMgmt
API is now fully
supported, but the plug-in is under technology preview.
Oracle Linux maintains user-space compatibility with Red Hat Enterprise Linux, which is independent of the kernel version that underlies the operating system. Existing applications in user space will continue to run unmodified on the Unbreakable Enterprise Kernel Release 5 (UEK R5) and no re-certifications are needed for RHEL certified applications.
To minimize impact on interoperability during releases, the Oracle Linux team works closely with third-party vendors whose hardware and software have dependencies on kernel modules. The kernel ABI for UEK R5 will remain unchanged in all subsequent updates to the initial release. UEK R5 contains changes to the kernel ABI relative to UEK R4 that require recompilation of third-party kernel modules on the system. Before installing UEK R5, verify its support status with your application vendor.
Table of Contents
This chapter describes issues that are fixed in Oracle Linux 7 Update 6.
Note that additional issues specific to the kernel that you are using might also be resolved. If you are using the default UEK R5, please see the Unbreakable Enterprise Kernel Release 5 Release Notes . If you are using an alternate UEK release or update, please refer to the appropriate release notes for this kernel version, available as part of the Unbreakable Enterprise Kernel Documentation Library .
Security fixes were applied to the OpenSSL packages that are shipped with Oracle Linux 7 and are included in this update release. These fixes also include a fix for CVE-2018-0739. (Bug ID 28584683)
An issue that caused
sosreport
to generate
errors within the
grub2-plugin-errors.txt
file when it was run on UEFI systems is resolved. (Bug ID
26586473)
A fix was applied to
grub2
to correct the
permissions of files within the
/boot/efi
directory. This fix resolves a conflict with another package,
but also resolves a longstanding issue where rpm verification
would flag files in this directory as having invalid file modes
affecting compliance with the United States Government Defense
Information Systems Agency (DISA) Security Technical
Implementation Guides (STIGs), as highlighted by the Security
Content Automation Protocol (SCAP). (Bug ID 27166026)

This chapter describes the known issues for Oracle Linux 7 Update 6.
Note that additional issues specific to the kernel that you are using might also be present. If you are using the default UEK R5 please see the Unbreakable Enterprise Kernel Release 5 Release Notes . If you are using an alternate UEK release or update, please refer to the appropriate release notes for this kernel version, available as part of the Unbreakable Enterprise Kernel Documentation Library .
The following issues might be encountered during an installation.
When performing a graphical installation, where some installation options are already set by using a kickstart configuration file, it is still possible to modify these settings by clicking the various fields during the installation to edit the predefined content. These types of edits during the installation process requires a user to intentionally attempt to modify the setting, effectively enabling an interactive installation, where options that are set in the kickstart configuration are not secured by any policy.
Note that this type of change is not possible when performing a text installation. During a text installation, the user can only modify fields that have not already been defined in the kickstart configuration file. (Bug ID 28642357)
When installing on an iSCSI disk, you must add either
ip=ibft
or
rd.iscsi.ibft=1
to the boot command line
and then specify at least one MBR or GPT-formatted disk as an
installation target. Otherwise, the installation fails with
the error message
No valid boot loader target device
found
. (Bug ID 22076589)
If you have not applied a Thin Persistence license to an HPE 3PAR storage array, installation fails to create a file system on a thin provisioned virtual volume (TPVV). This license is required to support the low-level SCSI UNMAP command for storage reclamation. If you do not have a suitable license, the workaround is to use a fully provisioned virtual volume (FPVV) instead of a TPVV. (Bug ID 22140852)
Installation fails if the target device is an Aura7 NVMe add-in card with two block devices. Although the card has two independent NVMe controllers and devices, they are assigned identical WWIDs. The multipath device mapper maps the two block devices to the same WWID, resulting in a bogus multipath configuration that prevents installation.
To work around the issue, disable multipath at boot for the
installation by using the installer boot argument
nompath
. After the installation, blacklist
the NVMe block devices for multipath configuration on the
system by editing
/etc/multipath.conf
, or
you can disable device mapper multipath altogether. See the
Oracle Linux Administrator's Guide for Release
7
at
https://docs.oracle.com/cd/E52668_01/E54669/html/index.html
for more information about configuring multipath. (Bug ID
27638939)
The following are known package conflicts for packages that are distributed by Oracle for Oracle Linux 7 through ULN or the Oracle Linux yum server.
In this release, a conflict between the
rdma-core
and
infiniband-diags
packages exists if you are
not installing the latest versions of these packages.
The conflict occurs when installing an older version of the
oracle-ofed-release
and
oracle-ofed-release-guest
packages, as RPM
detects the conflict and attempts to install
rdma-core-*
packages instead of RDMA, which
results in additional errors related to dependencies. For
example, the conflict is triggered when attempting to run the
following command:
# yum install oracle-ofed-release-guest-1.0.0-41.el7.x86_64
To avoid the conflict, use the
--exclude=rdma-core*
yum
option when performing this type of an installation. Note,
however, that Oracle recommends that you always use the latest
packages to resolve bugs and issues. See
Section 6.2, “Oracle-Supported RDMA Packages”
for more information about
installing the latest packages for RDMA. (Bug ID 26309256)
The
dovecot-devel.i686
and
dovecot-devel.x86_64
packages in the
ol7_x86_64_optional_latest
ULN channel
conflict. Attempting to install both packages results in a
transaction check error:
Transaction check error: file /usr/include/dovecot/config.h conflicts between attempted installs of dovecot-devel-1:2.2.10-7.el7.i686 and dovecot-devel-1:2.2.10-7.el7.x86_64
There are bitsize differences between the identified file. You may only install one of these packages on the same system at once. (Bug ID 25057633)
The
PackageKit.i686
package from the
ol7_x86_64_optional_latest
ULN channel
conflicts with the
PackageKit.x86_64
package in the
ol7_x86_64_u6_base

You may only install one of these packages on the same system
at once. To avoid the conflict, exclude the
PackageKit.i686
package in your
yum
configuration. For more information
about how to exclude packages, see the
Oracle
Linux Unbreakable Linux Network User's
Guide
.
(Bug ID 24963661)
The daemons and features that are provided by the Red Hat
Automatic Bug Reporting Tool (ABRT) are not supported in Oracle Linux.
ABRT packages and associated files, such as
libreport
, are included in the distribution
to satisfy package dependencies, but the features within these
packages are not supported. For technical assistance, contact
Oracle Support by accessing the My Oracle Support portal or by
telephone.
After upgrading from Oracle Linux 7 Update 4, the
libvirtd
process displays a warning message similar to following during
start-up:
libvirtd ... warning : virQEMUCapsInit:1211 : Failed to get host CPU cache info libvirtd ... warning : virLXCDriverCapsInit:85 : Failed to get host CPU cache info
You can safely ignore this warning. Note that this warning does not occur with a fresh installation. (Bug ID 27700583)
You cannot do snapshots of KVM guests if they use UEFI. In older
versions of QEMU and
libvirt
, the tools might
allow you to create the snapshot without an error or warning,
but the snapshot could be corrupted. More recent versions of
these tools prevent snapshot creation with an error similar to
the following:
virsh # snapshot-create-as OL7-seboot error: Operation not supported: internal snapshots of a VM with pflash based firmware are not supported
(Bug ID 26826800)
An Oracle Linux 7 KVM guest using the LSI MegaRAID SAS ISCSI controller is limited to 7 virtual disks. Although KVM guests can have up to 8 ISCSI virtual disks, the LSI MegaRAID SAS controller uses the first slot for the ISCSI Initiator, leaving just the 7 remaining slots for virtual disks.
The workaround for this issue is to use the
megasas
controller instead of the
lsi
controller when creating ISCSI virtual
disks. For example, change
-device lsi
to
-device megasas
, as shown in highlighted text
in the following example:
# /usr/bin/qemu-system-x86_64 -machine accel=kvm -m 8192 -smp 8 \
-drive file=/path/OracleLinux-7.6-x86_64.qcow2,format=qcow2,if=none,id=disk \
-device ide-hd,bus=ide.0,unit=0,drive=disk,bootindex=0 -device lsi,id=lsi0 \
-drive file=/path/disk1.img,format=raw,if=none,id=drive_image1 \
-device scsi-hd,id=image1,drive=drive_image1,bus=lsi0.0 \
...
# /usr/bin/qemu-system-x86_64 -machine accel=kvm -m 8192 -smp 8 \
-drive file=/path/OracleLinux-7.6-x86_64.qcow2,format=qcow2,if=none,id=disk \
-device ide-hd,bus=ide.0,unit=0,drive=disk,bootindex=0 -device megasas,id=lsi0 \
-drive file=/path/disk1.img,format=raw,if=none,id=drive_image1 \
-device scsi-hd,id=image1,drive=drive_image1,bus=lsi0.0 \

(Bug 27681238)
If
/boot
is hosted on a btrfs subvolume, GRUB
2 is unable to correctly process the
initramfs
and
vmlinuz
pathnames. This problem occurs when you update or install a new
kernel and
grubby
attempts to update the GRUB
2 configuration. In the case where you are running a fresh
installation of Oracle Linux 7 Update 6 and you upgrade the RHCK or UEK
kernel, the following error is displayed:
grubby fatal error: unable to find a suitable template
When the system is rebooted after the kernel update, the system boots to the old kernel.
Similarly, when upgrading from Oracle Linux 7 Update 4 to Oracle Linux 7 Update 6, if
/boot
is hosted on a btrfs subvolume, the
system boots to the old Oracle Linux 7 Update 4 kernel after the upgrade is
complete.
The workaround for this problem is to use
grub2-mkconfig
to regenerate the
/etc/grub2/grub.cfg
file immediately after
the kernel has been installed or upgraded, for example:
# grub2-mkconfig -o /boot/grub2/grub.cfg
Obtain a listing of the kernel menu entries in the generated configuration as follows:
# grep -P "submenu|^menuentry" /boot/grub2/grub.cfg | cut -d "'" -f2
From the listing, select the kernel entry that you want to run
as the default kernel and set this entry as the default using
the following command, substituting
menu entry
title
with the title of the kernel entry that you
identified in the listing:
# grub2-set-default "menu entry title"
You can use the
grub2-editenv list
command to
check that the
saved_entry
has been updated
with the selected kernel menu title.
Reboot and use uname -a to check that the correct kernel is now running.

Installing the
tex-fonts-hebrew
package fails
unless you first install all of the
texlive*
packages. (Bug ID 19059949)
The following are issues that you might encounter when using InfiniBand devices.
Kdump might fail on Oracle Linux 7 Update 6 if the Oracle Dual Port QDR InfiniBand Adapter M3 Firmware version 2.31.5350 is installed.
To prevent this issue from occurring, update the Oracle Dual Port QDR InfiniBand Adapter M3 Firmware version to at least 2.31.5350. (Bug ID 26351183)
You might see the following warning messages if you use the ibportstate disable command to disable an InfiniBand CA or router port:
ibwarn: [2696] _do_madrpc: recv failed: Connection timed out ibwarn: [2696] mad_rpc: _do_madrpc failed; dport (Lid 38) ibportstate: iberror: failed: smp set portinfo failed
You can safely ignore these warnings. (Bug ID 16248314)
If
RemoveIPC=yes
is configured for systemd,
interprocess communication (IPC) is terminated for a non-system
user's processes when that user logs out. This setting, which is
intended for use on laptop systems, can cause software problems
on server systems. For example, if the user is a database
software owner such as
oracle
for Oracle
Database, this configuration can cause a database installation
to fail or database services to crash.
By default, Oracle Linux 7 Update 6 configures
RemoveIPC=no
in
/etc/systemd/logind.conf
to prevent
systemd from terminating IPC. However, if you have touched this
file before updating your system to Oracle Linux 7 Update 6, the update installs
the new version of the file as
/etc/systemd/logind.conf.rpmnew
and does not
set
RemoveIPC=no
in
/etc/systemd/logind.conf
. To avoid database
crashes, set
RemoveIPC=no
in
/etc/systemd/logind.conf
and run the
systemctl reboot
command to reboot the
system. (Bug ID 22224874)
The creation of Oracle Linux 7 containers fails when the
root
file system
(
/container
) is hosted on an NFS share. This
problem occurs because the
iputils
package in
Oracle Linux 7 releases, (Updates 4 and 5) is built to use the Linux file
extended attributes
[xattr(7)] security
capabilities(7)
. Because the NFS protocol does not
support these file capabilities, the
iputils
package might not be installed into an NFS files system. For
example, when attempting to create an Oracle Linux 7 Update 4 container, the
installation fails while installing the
iputils
package, producing the following
error:
Error unpacking rpm package iputils-20121221-7.el7.x86_64 error: unpacking of archive failed on file /usr/bin/ping: cpio: cap_set_file error: iputils-20121221-7.el7.x86_64: install failed
Similar issues are seen when attempting to install the
initscripts
and
systemd
packages while creating an Oracle Linux 7 Update 3 container.
This issue occurs on both NFSv3 and NFSv4.
Note that Oracle Linux 6 containers are not affected. (Bug ID 25024258)
Oracle Linux 7 guests are supported for both hardware virtualization (HVM) and hardware virtualization with paravirtual drivers (PVHVM) on Oracle VM Release 3. Oracle Linux 7 guests in a paravirtualized domain (PVM) on Oracle VM or other Xen-based hypervisors are not supported.
Oracle Linux 7 guests of any type are not supported on Oracle VM Release 2. (Bug IDs 18712168, 18667813, 18266964)
The
hypervkvpd
and
hypervvssd
services fail to start if the
Hyper-V packages are at version
0-0.29.20160216git.el7
. This issue occurs on
Oracle Linux 7 guests that have the UEK R4 kernel running on a Windows
Hyper-V Server.
To resolve the issue, downgrade the package version for the
following packages to
0-0.26.20150402git.el7
:
hyperv-daemons
hyperv-daemons-license
hypervfcopyd
hypervkvpd
hypervvssd
These user-space packages are available in both the
ol7_latest
yum repository and in the
ol7_x86_64_UEKR4
ULN channel.
Follow these steps to resolve the issue:
Stop any running Hyper-V services:
#systemctl stop hypervfcopyd.service#systemctl stop hypervkvpd.service#systemctl stop hypervvssd.service
Downgrade the packages:
# yum downgrade hyperv*
Restart the Hyper-V services:
#systemctl restart hypervfcopyd.service#systemctl restart hypervkvpd.service#systemctl restart hypervvssd.service
Modify your yum configuration file to exclude the Hyper-V packages from future updates, for example:
# echo "exclude = hyperv*" >> /etc/yum.conf
Remember that you might want to remove this exclude at a later date when this issue is resolved.
(Bug ID 24745861)
The ip and iproute commands included with Oracle Linux 7 Update 6 include support for Geneve-capable devices. The module for this driver is included with the RHCK but is not included in UEK R4. The commands to set, add or view Geneve devices are only functional when used with the RHCK or with UEK R5. (Bug ID 24652835) .
When running UEK R4 on Oracle Linux 7 Update 6, NetworkManager fails to send a
response to low priority networks with DHCP on UEK R4. Networks
with higher priority (link-local, IPv6
fe80:/64
routes) take priority over the lower
priority networks. This behavior might result in the DHCPv6
server failing to send a response to a DHCP client on a lower
priority network, even if the network has another output device.
(Bug ID 27714775)
The network connection icon might report an active network
interface as being disconnected. This behavior is seen for the
root
user but not for other users.
Command-line utilities such as
ip link
and
ifconfig
report the correct state. (Bug ID
19060089)
By default, Oracle Linux 7 in graphical (GUI) console mode treats the hardware power button as equivalent to the ACPI "Sleep" button, which puts the system into low-power sleep mode. This behavior is specific to GNOME desktop environment.
In previous Oracle Linux versions, the hardware power button initiated a
system shutdown. To make Oracle Linux 7 do the same, create a file named
/etc/dconf/db/local.d/01-shutdown-button
with
the following content:
[org/gnome/settings-daemon/plugins/power] button-power='shutdown'
Then run the following command:
# dconf update
You must log out of the desktop environment and log back in for the new setting to take effect. (Bug ID 25597898)
The
libpcap
package is updated to enable
functionality for future technologies. If you install this
package and then attempt to uninstall it, a large number of
libvirt
packages might also be uninstalled
due to dependency relationships. The
libvirt
package has a dependency on the
libvirt-daemon-driver-nwfiler
package and
this package has a dependency on
libpcap
.
Removing
libpcap
removes the entire
libvirt
family of packages. (Bug ID 28582266)
When upgrading from a system prior to Oracle Linux 7 Update 4, where the
rdma-core.noarch
package is installed, 32-bit
versions of the packages and many dependencies are also
installed, unnecessarily. This problem occurs because the
original version of the package is obsoleted, and during
upgrade, the package is replaced with both the
rdma-core.i686
and
rdma-core.x86_64
versions of the package,
along with those packages' dependencies.
To work around the issue, run the
yum update
command with the
--exclude=\*.i686
option:
# yum update --exclude=\*.i686
(Bug ID 28217831)
A kernel panic can occur when
udev
attempts
to configure Oracle ASM disks. This issue is caused when
udevadm trigger
is run. The issue is caused
by a new udev rule that causes system CPUs to go offline after
the trigger.
You can re-enable CPUs by running the
chcpu -e
CPU
command to reset the
specified CPU. If all CPUs are off-lined, the kernel panics and
the system freezes. The disk device nodes are created and the
permissions are set appropriately after a reboot. (Bug ID
28638729)

You can download a full Oracle Linux 7 Update 6 installation media image from the Oracle Software Delivery Cloud at https://edelivery.oracle.com/linux . You can also obtain the latest Oracle Linux 7 packages from the Unbreakable Linux Network (ULN) and the Oracle Linux yum server.
You can install additional software for Oracle Linux 7 by subscribing to the different channels on ULN or by enabling the required repositories within your yum configuration. To explore the channels that are available to you on ULN, log in to https://uln.oracle.com/ and view the Channels option. To view the Oracle Linux yum repositories that are available for Oracle Linux 7, visit https://yum.oracle.com/oracle-linux-7.html .
The Oracle Linux yum server does not provide equivalent repositories for some channels that are available on ULN. These channels provide non-open source packages.
If you are installing an update on a system for which you have previously installed the Oracle-supported OFED packages, see Upgrading a system with an existing UEK R4 installation to continue to use UEK R4 for instructions on how to update these packages during an upgrade.
UEK R5 is the default boot kernel for fresh installations of Oracle Linux 7 Update 6. For more information, see the Unbreakable Enterprise Kernel Release 5 Release Notes .
For systems that are running UEK R3 or UEK R4 and are subscribed
to the
ol7_x86_64_UEKR3
or
ol7_x86_64_UEKR4
channel on ULN, or the
ol7_x86_64_UEKR3
or
ol7_x86_64_UEKR4
repository on the Oracle Linux yum
server, upgrade to the latest UEK release as follows:
Upgrade all of the packages on the system, including kernel packages.
# yum update
By default, the boot manager automatically enables the most recent kernel version so you do not need to change your GRUB configuration.
Reboot the system.
# systemctl reboot
Oracle Linux 7 Update 6 updates many major subsystems. To ensure that your updated systems function correctly, reboot them after updating.
It is possible to upgrade an Oracle Linux 6 system to Oracle Linux 7 Update 6 under the following conditions:
The system meets the minimum installation requirements for Oracle Linux 7 as described in Chapter 1, System Requirements and Limits .
The Oracle Linux 6 system has been completely updated from the
ol6_x86_64_latest
channel or
ol6_latest
repository.
UEK R3 or UEK R4 has been installed on the system to be upgraded and is the default boot kernel. Upgrading from UEK R2 is not supported. Note that the system is upgraded to use the UEK R5 release provided with Oracle Linux 7 Update 6.
No Oracle product stack is present on the system.
Upgrading is supported only for systems that are installed with the Minimal Install base environment. If additional packages are installed from an alternative repository or channel, upgrade might fail or the resulting upgrade might not function as expected.
General instructions on how to perform an upgrade are covered in Upgrading an Oracle Linux System in the Oracle Linux 7 Installation Guide .
The following is a summary of the steps that are specific to the update for this release:
Make sure that your system is completely up to date by using
the
yum update
command to update to the
latest Oracle Linux 6 release. The system must be subscribed to the
ol6_x86_64_latest
and
ol6_x86_64_addons
channels or
ol6_latest
and
ol6_addons
repositories to be updated.
Install the latest versions of the required upgrade packages:
# yum install openscap redhat-upgrade-tool preupgrade-assistant \
preupgrade-assistant-el6toel7 preupgrade-assistant-el6toel7-data-0 \
preupgrade-assistant-tools preupgrade-assistant-ui
Obtain the latest versions of these packages from ULN (in
the
ol6_x86_64_addons
channel), or from
the Oracle Linux yum server (in the
ol6_addons
repository).
If the system is registered with ULN, delete the system from ULN and disable yum plugins.
Run the preupg command to perform an upgrade assessment:
# preupg
Examine the results in
/root/preupgrade/result.html
to make sure
there are no items that have failed or need attention.
Run the redhat-upgrade-tool-cli command to perform the upgrade:
#redhat-upgrade-tool-cli --network=7.5 --instrepo=\OL7_repo_url--debuglog=/tmp/upgrade.log --cleanup-post
Replace
OL7_repo_url
with the URL
of the repository where the Oracle Linux 7 Update 6 ISO is hosted.
Reboot the system to start the upgrade process.
When upgrading from Oracle Linux 6 to Oracle Linux 7 Update 6, the previous version of UEK R4 is removed from the system during the upgrade and the system is updated to use the UEK R5 release that is provided on the installation media image as the default boot kernel.
Oracle Linux 7 Update 6 introduces UEK R5 as the default kernel. The Oracle-supported RDMA packages shipped with UEK R5 replace previous OFED packages and use an updated package and channel naming scheme. Oracle recommends using UEK R5 with Oracle Linux 7 Update 6. If you intend to install RDMA packages, please refer to the Unbreakable Enterprise Kernel Release 5 Release Notes .
If you are upgrading your system from a release prior to Oracle Linux 7 Update 6, and you are already using UEK R5 along with the Oracle-supported RDMA packages, these packages are updated automatically as part of the upgrade process.
If your system is registered with ULN, ensure that it is
subscribed to the
ol7_x86_64_UEKR5_RDMA
,
ol7_x86_64_UEKR5
, and
ol7_x86_64_latest
channels, before upgrade.
If your system uses the Oracle Linux yum server, ensure that the
ol7_UEKR5_RDMA
,
ol7_UEKR5
, and
ol7_latest
repositories are enabled before
upgrade.
If you are upgrading your system from a release prior to Oracle Linux 7 Update 6 and you are using UEK R4 with the Oracle-supported OFED packages, it is recommended that you upgrade to UEK R5 and change to use the corresponding Oracle-supported UEK R5 RDMA packages before you upgrade your system to Oracle Linux 7 Update 6.
Note that if the system is newly registered on ULN, the
ol7_x86_64_UEKR5
, and
ol7_x86_64_latest
channels are subscribed
by default. You may need to subscribe to the
ol7_x86_64_UEKR5_RDMA
manually.
If your system uses the Oracle Linux yum server, note that the
ol7_UEKR4
, and
ol7_latest
repositories are enabled by
default. You should ensure that the
ol7_UEKR5_RDMA
,
ol7_UEKR5
, and
ol7_latest
repositories are enabled before
upgrade.
Upgrade requires that you remove existing OFED packages prior to installing the compatible packages for UEK R5. Use the instructions in Unbreakable Enterprise Kernel Release 5 Release Notes for guidance on how to do this.
If you are upgrading your system from a release prior to Oracle Linux 7 Update 6 and you are using UEK R4 with the Oracle-supported OFED packages and you intend to continue to use UEK R4, you must ensure that your system is subscribed to the correct channels or that the correct yum repositories are enabled before you upgrade.
If you are using ULN, check that your system is registered
before you upgrade and subscribe the system to the
ol7_x86_64_UEKR4_OFED
,
ol7_x86_64_UEKR4
, and
ol7_x86_64_latest
channels on ULN.
By default, the
ol7_x86_64_UEKR5
and
ol7_x86_64_latest
channels are enabled
when you register Oracle Linux 7 Update 6 system with ULN. If the
ol7_x86_64_UEKR5
channel is enabled, you
must disable it to continue to use UEK R4 with the
Oracle-supported OFED packages.
If you are using the Oracle Linux yum server, check that the
ol7_latest
,
ol7_UEKR4
and
ol7_UEKR4_OFED
repositories are
enabled. Make sure that the
ol7_UEKR5
and
ol7_UEKR5_RDMA
repositories are disabled.
Use the yum update command to upgrade to Oracle Linux 7 Update 6 with the UEK R4 compatible OFED packages.
If you do not have any of the OFED packages installed, you can proceed to install the packages as described in the installation instructions provided in Unbreakable Enterprise Kernel Release 4 Update 7 Release Notes .
