We're attacking the docs with a vengeance now.  It's the last major 
showstopper for a 2.0 release...

Right, that's gotta go!  I vaguely remember seeing that some time before.

Xen doesn't overcommit memory, so you can't do that, no.  However, you could 
use the balloon driver to shift the memory allocation between domains at 
runtime (e.g. reduce dom0's memory footprint a little, then increase dom1's 
footprint instead).

Yes, it is a frequent query so it should be in there.  We'll add it whilst 
documentation updating...

Full release Real Soon Now (TM)!
