Well, I'm not doing much different than I was before we started the 
merge process, so I don't know what to tell you. The only different 
thing I know I am doing is that I have replaced 
/etc/xen/scripts/network-bridge with a null script to keep it from 
thrashing the networking.
I haven't seen the first error, before. The second error I've seen 
before, but only when I've done the "xm create" immediately after "xend 
start". My guess is that there is some kind of race with the 
initialization of xenstored, but I haven't chased it down.
