Rohit Yadav 52a98fa6cf CLOUDSTACK-8762: Check to confirm disk activity before starting a VM
Implements a VM volume/disk file activity checker that checks if QCOW2 file
has been changed before starting the VM. This is useful as a pessimistic
approach to save VMs that were running on faulty hosts that CloudStack could
try to launch on other hosts while the host was not cleanly fenced. This is
optional and available only if you enable the settings in agent.properties
file, on per-host basis.
