After upgrade of CNV , live migration of VM for workload update fails with 'operation failed: guest CPU doesn't match specification: missing features: pdcm'

According to `virsh capabilities` both source node and target node include   `pdcm`

This is urgent because it blocks the completion of CNV upgrade on https://bleeding.cnv.engineering.redhat.com/ and https://console-openshift-console.apps.cnv2.engineering.redhat.com/
