Transient disk support has been added to VDSM. A transient disk is a temporary qcow layer based on a volume that is attached to a virtual machine in read-write mode. All changes stored in the transient disk is lost when the disk is hot-unplugged or when the virtual machine shuts down. Its primary use is to access a disk snapshot (a read-only volume) in read-write mode.

Part of 3.3 Backup API flow Transient volume is now supported by vdsm. As part of the backup API feature, when we attach a disk snapshot to a dedicated machine with a backup software installed and plug it to this machine, a new transient volume is created by vdsm. This new volume enables vdsm to make changes on the RO attached disk snapshot. Checked during backup API feature testing. Tested on is21 and is23 (In reply to Elad from comment #3) > Transient volume is now supported by vdsm.
