New subject: [libvirt] [PATCH 1/3] vz: fix for tracking current snapshot
f1056279 removed virDomainSnapshotDef.current and leaved
using vm->current_snapshot only. Later 4819f54bd moved current snapshot
tracking to virDomainSnapshotObjList. As vz driver never used
vm->current_snaphot this patch includes fixes after both commits.
