Noticed when testing new libvirt against old qemu that lacked the snapshot_blkdev HMP command. Libvirt was mistakenly treating the command as successful, and re-writing the domain XML to use the just-created 0-byte file, rendering the domain broken on restart. * src/qemu/qemu_monitor_text.c (qemuMonitorTextDiskSnapshot): Notice another possible error message. * src/qemu/qemu_driver.c (qemuDomainSnapshotCreateSingleDiskActive): Don't keep 0-byte file on failure.
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.
