  • Issues: After an 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

  • Issues: Network-scripts networking management has been deprecated in EL9. NetworkManager is now used. It isn't supported by OnApp.
    Because of that:
    • Assigning multiple IP addresses won't work.
    • Changing Primary IP Address with Rebuild Network (via OnApp UI) will require manual actions in VS's main console:

      # /etc/rc.d/init.d/el9NM2onapp start
      # nmcli dev reapply eth0
  • Limitation: KVM VSs based on the template should be configured with the correct CPU model. The reason is that glibc-2.34-20 includes a fix to more reliable detect CPU compatibility. See the bug information at https://bugzilla.redhat.com/show_bug.cgi?id=2040657. Such detection generates the following inside the guest:
    "Fatal glibc error: CPU does not support x86-64-v2".
    To configure the correct CPU model, refer to <Configure CPU Model>.
