You’re running this as a domU, correct? What is crashing, the
domU or the dom0?

Thanks Nathan,
I'm running a w2k8 with 20 gb of ram, I'm asking because my server freezes or
reboots (usually without any message on console or logs)
My server has 48GB of memory so the memory doesn't should be a problem...
Any ideas ??

To clarify, as I have now had multiple people email me
off-list:
You'd need 20.25 GB installed so that you have memory for the Dom0. Since
you're unlikely to install this amount of memory (your next likely RAM quantity
would be 24GB), there's no problem. My point was just that you can't
forget that Dom0 and the hypervisor are their own systems, and need memory to
function. :)
Also, I had someone ask about whether Windows would see it (due to the
oft-misunderstood memory 'limitations' of 32-bit Windows) - this link is handy.

So you'll either want to use Enterprise or Datacenter (which support 64GB of
memory in 32bit mode), or use a 64-bit version of any edition. I've heard
reports that 64bit Windows seems to perform better in HVM than 32 bit, so that
might be a good idea anyways.
