To be clear, it doesn't break consoleproxy for me, but it breaks migration as wido mentions in his long first post. I think he intended to fix it with the new libvirt 0.5.0 bindings rather than roll back, but it didn't happen before the cut. It should probably be rolled back on both 4.1 and master at this point, lest it be forgotten, and he can add it back in once we for certain have the new libvirt bindings and fix.
