CentOS Linux 8.0 x64
Template label | Operating system | OS release | OS arch | Virtualization | Version |
|---|---|---|---|---|---|
CentOS 8.0 x64 | CentOS Linux | 8.0 | x64 | kvm, kvm_virtio | 1.0 - 1.3 |
Issues: After operating system upgrade (with 'yum update') and before reboot, please check and modify GRUB_ENABLE_BLSCFG option's value (set it into 'false',) in GRUB2 boot loader's default configuration file /etc/default/grub. Then generate new GRUB2 boot loader's main config with:
# grub2-mkconfig -o /boot/grub2/grub.cfg
Reboot the system (if required).
- Limitation: The template isn't compatible with Xen. Red Hat Enterprise Linux release 8.x and its clones (like CentOS Linux) can't run as Xen PV DomU (the kind of model OnApp runs Linux guests) anymore. Xen PV guest support has been disabled for all 8.x releases.
Technical details:
# cat /etc/redhat-release CentOS Linux release 8.0.1905 (Core) # uname -r 4.18.0-80.7.1.el8_0.x86_64 # grep -i CONFIG_XEN_PV /boot/config-`uname -r` # CONFIG_XEN_PV is not set
The reason is CONFIG_XEN_PV Linux kernel configuration item (was introduced in Linux kernel versions >= *4.12*) unset on the kernel;
prompt: Xen PV guest support
type: bool
depends on: CONFIG_XEN
defined in arch/x86/xen/Kconfig
found in Linux kernels: 4.12–4.20, 5.0–5.2, 5.3-rc+HEAD

Reboot the system (if required).
- Limitation: Using the kernel-ml may expose your system to security, performance and/or data corruption issues. Since timely updates may not be available from the ELRepo Project, the end user has the ultimate responsibility for deciding whether to continue using the kernel-ml packages in regular service. These packages are not signed for SecureBoot.
