I'm running CentOS 5.1 with all updates, and the xen kernel. For some
reason the OS is not seeing the full amount of ram.
#uname -a
Linux CentOS-VM-A 2.6.18-53.1.21.el5xen #1 SMP Tue May 20 10:03:27 EDT

On another box with identical hardware, I see
# free

Swap: 2031608 152 2031456
Both of these boxes have 8GB of ram. Is there a reason I'm not seeing
all of it?
