Hi, is there a simple way to check that we're running under a domU? So
far I came up with:

[[ -d /proc/xen && ! -z `ls /sys/bus/xen/devices/` ]]

or

-e /sys/bus/xen/drivers/vbd || -e /sys/bus/xen/drivers/vif

Neither of which is pretty, and I'm not convinced they work under all
circumstances. This is useful for system setup scripts to do different
things depending if they are run under dom0/U.

Thanks,
Chris
