Qemu unfortunately doesn't update internal state right after migration and so the actual balloon size as returned by 'query-balloon' are invalid for a while after the CPUs are started after migration. If we'd refresh our internal state at this point we would report invalid current memory size until the next balloon event would arrive. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1242940
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.
