There are two main parts to nested KVM.
1st the host must have it enabled, so put host in maintenance mode through
engine UI, set boot option to add it, go to UI
host 'installation'->reinstall to pick up the changes and reboot, or is it
reboot and then reinstall, I forget.
2nd part is enabling the VM in the VM edit dialog by setting 'Host' CPU
option Pass-Through for the VM.

Already tried the instructions to enable nested virtualization on
described above including reboot.
Even got the following output from host
But from vm trying to verify vm has enabled virtualization running command
expecting to get
INFO: /dev/kvm exists
KVM acceleration can be used
but instead get the following:
INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used
I guess requires additional change so I tried to follow up. According
withdocumentation around this topic need to set nested virtualization in
vort-manager but only found how to do it in other patforms instead oVirt.
Do you have idea how to do it?
