Which bootloader are you using to boot Xen? It's the bootloader which provides the memory map.
I'm using Grub.
grub --version
grub (GNU GRUB 0.97)
Someone suggested getting grub to display the memory map, which shows this.
grub> displaymem
displaymem
EISA Memory BIOS Interface is present
Address Map BIOS Interface is present
Lower memory: 640K, Upper memory (to first chipset hole): 3072K
[Address Range Descriptor entries immediately follow (values are 64-bit)]
Usable RAM: Base Address: 0x0 X 4GB + 0x0,
Length: 0x0 X 4GB + 0xa0000 bytes
Reserved: Base Address: 0x0 X 4GB + 0xa0000,
Length: 0x0 X 4GB + 0x60000 bytes
Usable RAM: Base Address: 0x0 X 4GB + 0x100000,
Length: 0x0 X 4GB + 0x300000 bytes
Does that look right ?
My boot entry in menu.lst is:
title Xen 3.0.3 (kernel 2.6.16 + xensource) [*** Option B ***]
kernel /boot/xen-3.0.3-0.gz dom0_mem=262144 com1=115200,8n1
console=vga,com1
module /boot/vmlinuz-2.6.16.29-xen0 root=/dev/md0 ro
console=tty0 console=ttyS0
