Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

https://bugzilla.redhat.com/show_bug.cgi?id=727709 mentions that if qemu fails to create the snapshot (such as what happens on Fedora 15 qemu, which has qmp but where savevm is only in hmp, and where libvirt is old enough to not try the hmp fallback), then 'virsh snapshot-list dom' will show a garbage snapshot entry, and the libvirt internal directory for storing snapshot metadata will have a bogus file. This fixes the fallout bug of polluting the snapshot-list with garbage on failure (the root cause of the F15 bug of not having fallback to hmp has already been fixed in newer libvirt releases). * src/qemu/qemu_driver.c (qemuDomainSnapshotCreateXML): Allocate memory before making snapshot, and cleanup on failure. Don't dereference NULL if transient domain exited during snapshot creation. |

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.
