@miguelaferreira okay, I'll see what I can do. I'm also exploring other
ways to detech if the vm disk file has changed, using an exhaustive checksum
comparison for example as file attributes cannot be trusted for nfs partitions
that were mounted with noatime. I would also like to discuss perhaps here, if
anyone has better ideas or suggestions.

> 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.
