Comment 0 for bug 1540251

Steps To Reproduce:
1. Deploy OpenStack cluster with 3 controllers and 1 compute node (Ubuntu)
2. Add RHEL-based or CentOS-based compute node to the cluster
3. Check the cluster health, it will work fine.
4. Shutdown non-Ubuntu compute node and power on this node
5. Check the hypervisor status and libvirt process status on compute node

Expected Result:
Compute node should work fine after power cycle.

Observed Result:
libvirt process is down, hyper visor status is "down":

[root@rhel-1 ~]# virsh list
error: failed to connect to the hypervisor
error: no valid connection
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory
