My guess on that issue would be that something is causing domains not to be
fully destroyed, and then it takes an 'xm create' to make xend forcibly
forget about the zombie domain. Yet presumably it still hangs around. I
haven't reproed anything like this, but I'm not using your drivers and I
don't know whether you are using 64b or 32b Xen.
