Redefining a qemu snapshot requires a bit of a tweak to the common snapshot parsing code, but the end result is quite nice. Be careful that redefinitions do not introduce circular parent chains. Also, we don't want to allow conversion between online and offline existing snapshots. We could probably do some more validation for snapshots that don't already exist to make sure they are even feasible, by parsing qemu-img output, but that can come later. * src/conf/domain_conf.h (virDomainSnapshotParseFlags): New internal flags. * src/conf/domain_conf.c (virDomainSnapshotDefParseString): Alter signature to take internal flags. * src/esx/esx_driver.c (esxDomainSnapshotCreateXML): Update caller. * src/vbox/vbox_tmpl.c (vboxDomainSnapshotCreateXML): Likewise. * src/qemu/qemu_driver.c (qemuDomainSnapshotCreateXML): Support new public flags.
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.
