Once your VM is under cluster control, you should use the cluster commands
to start, stop or migrate it. Using a combination of Cluster and virsh
commands can result in a corrupt VM disk image as you can end up with the
VM running on multiple nodes at the same time.
I messed this up once while bui
multipath devices of your
PVs.

How many paths doe you currently have to your disk?
Does your LVM use the multipath name (mpath0)?

Your physical volume can be a whole disk (mpath0) or a partition (mpath0p1). I
use the partition schema as blank disks could be accidentally used by a follow
on admin who does not fully understand the system configuration.
