> 256MB for dom0, rest split up for the 2 domU would be my guess.

If you're running a light dom0 that's not running lots of other services / 
apps, that'd be a good place to start testing (then raise this, if 
necessary).  I'd have thought it ought to run OK.

I generally recommend people set dom0's memory on the Xen command line (using 
dom0_mem=) rather than ballooning it to the right size.  Extensive ballooning 
has been known in the past to cause Linux to get confused; you really don't 
want Linux acting up in dom0, so I generally recommend people cut the 
ballooning out altogether.


Dave: Just a question. What use is a unicyle with no seat?  And no pedals!
Mark: To answer a question with a question: What use is a skateboard?
Dave: Skateboards have wheels.
Mark: My wheel has a wheel!
