Create VM with "oracle linux 9.6" as "Operating System", the "Emulated Machine" generated is "pc-i440fx-rhel7.6.0", which cannot choose "UEFI" as firmware.

Create VM with "oracle linux 9.6" as "Operating System", the "Emulated Machine" generated is "pc-i440fx-rhel7.6.0", when I try to change firmware to "UEFI" and save, I got the error message:

Failed to change firmware
operation failed: Unable to find 'efi' firmware that is compatible with the current configuration

The problem doesn't exist for all other oracle linux versions, as the "Emulated Machine" generated is pc-q35-rhel9.6.0.

This indicates you miss some essential packages which you need to install from your distro package manager. I can't tell you how they are called as you didn't include on what OS you run Cockpit.

Thanks for your help. Cocopit and KVM are installed on oracle linux 9.6.
cat /etc/oracle-release
Oracle Linux Server release 9.6

The interesting observation is that if I choose other oracle linux versions like ol9.4 and ol10 when creating VM, the error message won't appear, I can save "UEFI" option for firmware.

seems the problem is not with cockpit. When using "virt-install --name test1 --memory 1024 --vcpus 1 --os-variant=ol9.6 --disk path=/vmdata1,size=20,bus=scsi --print-xml", the output XML shows incorrect machine type.

You might want to reach out to Oracle support then or osinfo-db which should have the definitions.
