Description Barak 2023-06-28 12:06:22 UTC 
Description of problem:
There is a QEMU && libvirt conflict regarding which features are needed to run a vmi with named CPU model.
To solve this we need to support a CPU model only if we have the requirements by both libvirt and qemu.



Version-Release number of selected component (if applicable):


How reproducible:
Try to create VMI with `x86_Icelake` when mpx is missing on the nodes.

Steps to Reproduce:
1.
2.
3.

Actual results:
VMI creation will fail with libvirt error

Expected results:
The node shouldn't have label for `x86_Icelake` in that case and virt-launcher pod shouldn't be scheduled.

Comment 1 Kedar Bidarkar 2023-07-24 10:04:32 UTC 
Verification requires very specific hardware, we don't have such servers in QE.

It is covered by unit tests, so moving it to Verified state.
