Neat. We also have a (possibly not quite working) UML driver in
libvirt which I added mostly for fun. I wonder what work libvirt
UML would require in order to support libguestfs usage.

There's plenty of scope for integrating the libvirt UML driver with 
libvirt's auditing, svirt, and cgroups infrastructure too, if anyone
thinks UML is still actually useful in the real world.
