Based on the console errors I've seen when I have a kernel panic, and 
some of the open bug reports I've seen, I'm guessing that cpu pinning 
would solve my immediate problem.
But I'm not sure what an effective configuration would be - my current 
environment has 2 CPUs and 5 VMs (dom0 + 4 domUs) per server.  Not sure 
how to set up the pinning, and I expect there would be a performance 
hit.  So much easier to let the hypervisor allocate CPUs dynamically - 
if it worked right.
Sam... could you say a bit more about the configuration details of what 
you're doing re. "cpu pinning and better ram management?"
Thanks,

Miles
