Once the domains are up I haven't seen any additional problems.  I seem to 
be finally getting the networking under control by using standard FC4 init 
scripts. I'm not sure what I was getting wrong with the networking 
previously.

The current issue I have is that my test domainU fails to start every time 
after dom0 is started (log below). It starts on the second and subsequent 
restarts. I tried pulling the LVM/Raid support out of the XenU kernel, but 
it didn't help. The root being passed to the domU in the log is a LVM volume 
('phy:/dev/VolGroup00/root01xenu,sda1,w').
