Hmm, I've not seen a real need for this so far. (Halting the guest and relaunching it from the shell with lkvm was fast enough for my tests ;-) But it's worth to get it working.

Still kept the pci stuff as a separate patch in case that it might be replaced with something based on "PCI: Generic Configuration Access Mechanism support" (https://lkml.org/lkml/2014/5/18/54) or similar.
