[Qemu-devel] [PATCH] blockdev-backup: enable non-root nodes for backup

2017-11-09 Thread Vladimir Sementsov-Ogievskiy
This is needed to implement image-fleecing scheme, when we create a temporary node, mark our active node to be backing for the temp, and start backup(sync=none) from active node to the temp node. Temp node then represents a kind of snapshot and may be used for external backup through NBD.
