Unlike savevm, the qmp_transaction interface will not generate snapshot name automatically, saving trouble to return information of the new created snapshot. Although qcow2 support storing multiple snapshots with same name but different ID, here it will fail when an snapshot with that name already exist before the operation. Format such as rbd do not support ID at all, and in most case, it means trouble to user when he faces multiple snapshots with same name, so ban that case. Request with empty name will be rejected. Snapshot ID can't be specified in this interface. Signed-off-by: NWenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>
