Eric Blake 4e9953a426 snapshot: allow reuse of existing files in disk snapshot ... When disk snapshots were first implemented, libvirt blindly refused to allow an external snapshot destination that already exists, since qemu will blindly overwrite the contents of that file during the snapshot_blkdev monitor command, and we don't like a default of data loss by default. But VDSM has a scenario where NFS permissions are intentionally set so that the destination file can only be created by the management machine, and not the machine where the guest is running, so that libvirt will necessarily see the destination file already existing; adding a flag will allow VDSM to force the file reuse without libvirt complaining of possible data loss. https://bugzilla.redhat.com/show_bug.cgi?id=767104 * include/libvirt/libvirt.h.in (virDomainSnapshotCreateFlags): Add VIR_DOMAIN_SNAPSHOT_CREATE_REUSE_EXT. * src/libvirt.c (virDomainSnapshotCreateXML): Document it. Add note about partial failure. * tools/virsh.c (cmdSnapshotCreate, cmdSnapshotCreateAs): Add new flag. * tools/virsh.pod (snapshot-create, snapshot-create-as): Document it. * src/qemu/qemu_driver.c (qemuDomainSnapshotDiskPrepare) (qemuDomainSnapshotCreateXML): Implement the new flag.		2012-01-10 11:53:23 -07:00
