migration: Don't activate block devices if using -S
Activating the block devices causes the locks to be taken on the backing file. If we're running with -S and the destination libvirt hasn't started the destination with 'cont', it's expecting the locks are still untaken. Don't activate the block devices if we're not going to autostart the VM; 'cont' already will do that anyway. This change is tied to the new migration capability 'late-block-activate' that defaults to off, keeping the old behaviour by default. bz: https://bugzilla.redhat.com/show_bug.cgi?id=1560854Signed-off-by: NDr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: NJuan Quintela <quintela@redhat.com> Signed-off-by: NJuan Quintela <quintela@redhat.com>
