Can you capture the

  /var/cache/libvirt/qemu/capabilities/926803a9278e445ec919c2b6cbd8c1c449c75b26dcb1686b774314180376c725.xml' 

from the virt-handler and virt-launcher pods. It contains a <cpuid>
block that will show us the differences libvirt recored, /after/,
libvirt has done its filtering. This will show if there si more
we need to filter.

Done. Only attached the one from handler since it is 100% identical to the launcher.

Let me know if you need more information.

Thanks and best regards,

Roman

They'll all end up at the same caching scode so should not make any
difference.
