Migration to an older libvirt (pre v1.3.0-175-g7140807) is broken
because older versions of libvirt generated different channel paths and
they didn't drop the default paths when parsing domain XMLs. We'd get
such a nice error message:
internal error: process exited while connecting to monitor:
2016-07-08T15:28:02.665706Z qemu-kvm: -chardev socket,
id=charchannel0,path=/var/lib/libvirt/qemu/channel/target/
domain-3-nest/org.qemu.guest_agent.0,server,nowait: Failed to bind
socket to /var/lib/libvirt/qemu/channel/target/domain-3-nest/
org.qemu.guest_agent.0: No such file or directory
That said, we should not even format the default paths when generating a
migratable XML.

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.
