https://bugzilla.redhat.com/show_bug.cgi?id=876829 complains that if a guest is put into S3 state (such as via virsh dompmsuspend) and then an external snapshot is taken, qemu forcefully transitions the domain to paused, but libvirt doesn't reflect that change internally. Thus, a user has to use 'virsh suspend' to get libvirt back in sync with qemu state, and if the user doesn't know this trick, then the guest appears hung. * src/qemu/qemu_driver.c (qemuDomainSnapshotCreateActiveExternal): Track fact that qemu wakes up a suspended domain on migration.
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.
