    Seems, good, but, all the logging is debug. Isn't there something which we 
have to print on info or error here?
    
    We want to make sure that we also print useful stuff on info or error, not 
all systems should run on debug in production.

> 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.
