Commit b3f2b4ca5cfe98b08ffdb96f0455e3e333e5ace6 left buf unallocated in the case of QMP capability probing being used, leading to a segfault in strlen in the cleanup path. This patch opens the log and allocates the buffer if QMP probing was used, so we can display the helpful error message.
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.
