 Is there a reason to use xen 2 on the RH server instead of xen 3 ?
I'm pretty sure xen 3 would work too (I haven't used RHEL 3 as a dom0
for a while though...).

 I've had problems with the auto-generated initrd file on some
servers too. What I usually do is:
 - boot with the regular RHEL kernel
 - do a 'lsmod' to see the loaded modules and write down the ones
related to SCSI/SATA/SAS controllers and disks
 - rebuild the xen initrd with 'mkinitrd -v --with=<module-1>
--with=<module-2> -f /boot/initrd-<version> <version>', adding the
necessary modules
 - reboot and enjoy :)

 If you don't know what modules to add, you can send the output of
'lsmod' and I'll try to see what's needed.
