I think libvirt needs some work to accommodate migration V2... So after shaving a bunch of yakks wrt getting my test boxes setup I've finally tracked this one down... libvirt is passing libxl a restore (and perhaps save) file descriptor which is set O_NONBLOCK, which libxl/c doesn't expect and therefore doesn't handle the resulting EAGAIN. Ian and I think it would be more convenient for most callers if libxl took care of this by making the fd blocking again and returning it to the original state when it was done. I'll cook up a patch. I think migr v1 probably had the same requirement, although it may not have manifested itself as a bug.
