For the curious:
The bug seems to have come in between 4.0.0 rc1 (20789) and 20822.
Bisecting between those is more fun because PV domain creation and migration
were broken in libxc then. Reverting 20808 (the only cset there that
touches the shadow code) doesn't fix the problem.
Selective backporting yesterday seemed to blame 20812 ("xend: NUMA: fix
division by zero on unpopulated nodes"), which seems unlikely. I'll dig
further.
Tim.
