Wouldn't this block best be refactored into a separate method?

> KVM hosts have real issue with fencing when storage are accessible by
> multiple hosts such as in the case of NFS, in which case there is a
> possibility of qcow2 disks being accessed by multiple hosts causing disk
> corruptions. The aim of this ticket is to explore ways to delay starting a VM
> if the qcow2 disks/files are still being accessed.
