my own server is running xen over centos 5... it's an old compaq  
DL360, dual 1GHz processors, 3.5GB RAM, dual 147GB HDs in a hardware  
RAID-1. it has six sessions running all the time, with another one  
that i can start and stop as needed in order to test things.

the only real problem i had was when the hardware rebooted, it was  
starting with all 3.5GB of RAM allocated to the xen0 session, and as  
the others started, the hypervisor had to take it away from xen0 and  
give it to the new child, which works if you wait until each child is  
fully booted before starting the next one... i added a parameter to  
the kernel's command line (in the grub.conf) which told the hypervisor  
to only allocate 512MB to the xen0, and the children all start cleanly  
now.

i got a decent start on documenting the whole thing, but i seem to  
think it's not done yet, and without looking at it, i don't remember  
exactly what's missing. you're free to look at what i have so far  
though...
