Oracle VM does not see all physical memory

CentinulOct 13 2010 — edited Oct 18 2010

I'm running Oracle VM 2.2.1 on a box with a quad core Intel i5-750, and 8GB (4 x 2GB) of physical RAM.

Unfortunately I cannot get Xen to recognize all 8GB. I've tried my best to investigate but I'm at a loss. For starters the BIOS reports all 8GB.

Here is various pieces of information to hopefully help:

Thanks for all the help
