Dear Kiv, It seems that you have hosts with different CPus in the same cluster - which shouldn't happen.In your case the HE is on host with Intel SandyBridge IBRS SSBD Family , but you have no other host with that CPU. Can you power off and edit the CPU of this VM to match the rest of the Host CPUs ?usually the older the CPU type on the VM - the higher compatibility it has , but performance drops - so keep that in mind.

Just to confirm, the entire cluster is set to Westmere as the CPU type? Can you please attach vdsm logs and libvirt logs from the host you are trying to migrate to?
