In order to distinguish disk snapshots from system checkpoints, a new state value that is only valid for snapshots is helpful. * include/libvirt/libvirt.h.in (VIR_DOMAIN_LAST): New placeholder. * src/conf/domain_conf.h (virDomainSnapshotState): New enum mapping. (VIR_DOMAIN_DISK_SNAPSHOT): New internal enum value. * src/conf/domain_conf.c (virDomainState): Use placeholder. (virDomainSnapshotState): Extend mapping by one for use in snapshot. (virDomainSnapshotDefParseString, virDomainSnapshotDefFormat): Handle new state. (virDomainObjSetState, virDomainStateReasonToString) (virDomainStateReasonFromString): Avoid compiler warnings. * tools/virsh.c (vshDomainState, vshDomainStateReasonToString): Likewise. * src/libvirt_private.syms (domain_conf.h): Export new functions. * docs/schemas/domainsnapshot.rng: Tighten state definition. * docs/formatsnapshot.html.in: Document it. * tests/domainsnapshotxml2xmlout/disk_snapshot.xml: New test.
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.
