Eric Blake 3d77d0a644 snapshot: introduce new deletion flag ... Reverting to a state prior to an external snapshot risks corrupting any other branches in the snapshot hierarchy that were using the snapshot as a read-only backing file. So disk snapshot code will default to preventing reverting to a snapshot that has any children, meaning that deleting just the children of a snapshot becomes a useful operation in preparing that snapshot for being a future reversion target. The code for the new flag is simple - it's one less deletion, plus a tweak to keep the current snapshot correct. * include/libvirt/libvirt.h.in (VIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN_ONLY): New flag. * src/libvirt.c (virDomainSnapshotDelete): Document it, and enforce mutual exclusion. * src/qemu/qemu_driver.c (qemuDomainSnapshotDelete): Implement it.		2011-09-05 07:03:04 -06:00
