      Create 2-3 (depends on the number of nodes) vms with numa passthrough enabled, each VM should be running on separate node (nodes has to have enough resources for 2 VMs on the same node). Trigger live migration of VM1, so it is moved to the same node as VM2. Live migration fails with error: virError(Code=27, Domain=20, Message='XML error: Argument 'cellid' in memnode element must correspond to existing guest's NUMA cell')

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