Since libvirt for dubious historical reasons stores memory size as kibibytes, it's possible that the alignments done in the qemu code overflow the the maximum representable size in bytes. The XML parser code handles them in bytes in some stages. Prevent this by doing overflow checks when alinging the size and add a test case.

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.
