For disk snapshots, the user could request an external snapshot but not supply a filename; later on, we would check this condition and generate a suitable name if possible, or gracefully error out when not possible (such as when the original file was a block device). But unless we come up with a suitable way to generate external memory file names, we have no later code point that was checking for NULL, so we should forbid this up front. * src/conf/snapshot_conf.c (virDomainSnapshotDefParseString): Avoid NULL deref, since we don't generate names yet.
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.
