And you are sure you have 2GB of memory? What's in /boot/grub/menu.lst?

Smile Thank you for reply

I am sure i have 2 GB, in windows I could see them.
title Xen 3.3 / Ubuntu 8.10, kernel 2.6.27.5
root (hd0,0)
kernel /boot/xen-3.3.gz
module /boot/vmlinuz-2.6.27.5 root=/dev/mapper/pdc_cffhehibfd1 ro mem=2011M console=tty0
module /boot/initrd.img-2.6.27.5

Without mem variable the same result
Than you.

Hm, not sure what it is... Do you see any memory-related messages during startup (or in the
Code:
dmesg
output)?

The "less" memory showing is because of Xen. Xen takes a chunk of memory and hides it from the system(own use). On my box with 4G of ram and no VM's started, free -m shows a total of 3770Megs.
