Wire up the new snapshot creation flags in virsh. For convenience, teach 'snapshot-current' how to make an existing snapshot become current (can be used after upgrading to newer libvirt to recover from the fact that the older libvirt lost track of the current snapshot after a restart). The snapshot-create-as command is intentionally not taught --redefine or --current, as this would imply adding a lot of other options for everything else that can appear in the <domainsnapshot> xml, but which is normally read-only. Besides, redefining will usually be done on files created by snapshot-dumpxml, rather than something built up by hand on the command line. And now that we can redefine, we can edit. * tools/virsh.c (cmdSnapshotCreate): Add --redefine, --current, and --no-metadata. (cmdSnapshotCreateAs): Add --no-metadata. (cmdSnapshotCurrent): Add snapshotname to alter current snapshot. (cmdSnapshotEdit): New command. * tools/virsh.pod (snapshot-create, snapshot-create-as) (snapshot-current, snapshot-edit): Document these.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
