Pretty sure it didnt detect the drives, booting the same kernel on
bare metal detects the hd (WD360GD-00FLA2), which proves that the
kernel has the correct drivers, in both ahci and legacy mode the
kernel works on the bare metal but not under Xen.
dmesg from the same kernel without xen:

root is a physical partition (sda2)
I will not be at work until tuesday and I want to continue to work on
this, so I wonder if anybody could tell me how to setup xen and linux
such that any oops/crash/failure to mount root filesystem results in a
reboot? I have a serial console setup which I can access remotely, but
I have no way to reset or power cycle the system.
