Audit all changes to the qemu vm->current_snapshot, and make them update the saved xml file for both the previous and the new snapshot, so that there is always at most one snapshot with <active>1</active> in the xml, and that snapshot is used as the current snapshot even across libvirtd restarts. This patch does not fix the case of virDomainSnapshotDelete(,CHILDREN) where one of the children is the current snapshot; that will be later. * src/conf/domain_conf.h (_virDomainSnapshotDef): Alter member type and name. * src/conf/domain_conf.c (virDomainSnapshotDefParseString) (virDomainSnapshotDefFormat): Update clients. * docs/schemas/domainsnapshot.rng: Tighten rng. * src/qemu/qemu_driver.c (qemuDomainSnapshotLoad): Reload current snapshot. (qemuDomainSnapshotCreateXML, qemuDomainRevertToSnapshot) (qemuDomainSnapshotDiscard): Track current snapshot.
