The pointer to the xml describing the domain is saved into an object prior to calling VIR_REALLOC_N() to make the size of the memory it points to a multiple of QEMU_MONITOR_MIGRATE_TO_FILE_BS. If that operation needs to allocate new memory, the pointer that was saved is no longer valid. To avoid this situation, adjust the size *before* saving the pointer. (This showed up when experimenting with very large values of QEMU_MONITOR_MIGRATE_TO_FILE_BS).
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.
