Description of problem:
Follow the guidance on the web page to create and run the VM. Start the migration, but it fails very soon, and the VMI reports an error： reason:Live migration failed error encountered during MigrateToURI3 libvirt api call: virError(Code=9, Domain=31, Message='operation failed: guest CPU doesn't match specification: missing features: vmx-rdseed-exit') Each node is configured identically. The VMI uses ocs-storagecluster-ceph-rbd-virtualization and is set to use the host-model CPU configuration.
Version-Release number of selected component (if applicable):
Openshift version: 4.16.0-rc.4 CNV version: 4.16.0 HCO image: brew.registry.redhat.io/rh-osbs/iib:737387 OCS version: 4.16.0-126.stable
How reproducible:
100%
Steps to Reproduce:
1. Create a VM (rhel9, u1.small) from InstanceType and wait till it's up. 2. Click Actions: migrate on a different node. 3. Check VM, VMI and virt-launcher pod.
Actual results:
VM starts to migrate but fails immediately.

Expected results:
VM is migrated to a different node and keeps running.
