I did try it out (see "maximum Number of DomUs" posting a few months
back) on a 16 GB Quad-Opteron, and was surprised hitting a limit
way before I used up all my memory, at about 107 DomUs. Xen has a
private heap of 16MB and each Domain needs some memory there, so
(possibly depending of what else is stored there) at about 100 DomUs
that's it.
Sure, not a real problem (there are few usefull szenarios in which
one would want 100 DomUs on one host), but worth mentioning IMHO...
Or did something change in this respect?
