......................................................................
reduce the time VM is paused in snapshot with RAM creation
By using libvirt's VIR_DOMAIN_SNAPSHOT_CREATE_LIVE flag we minimize the
time the VM is switched to paused state while creating live snapshot
with RAM. Without this flag the VM is switched to pause state for the
whole process of dumping the memory, and with this flag the VM is
switched to pause state only for a short time.
