Hi Andrew,

thanks for your tip.

Now I can easily determine wether I'm running
on a modified kernel or not (by checking for
the presence of /proc/xen).

However, once I've found that, I'd like to know
if I'm on a priviledged domain or not.

Sadly my /proc/xen/capabilities is only readable
by root.

What would be a clean way to check for this from
a normal user account?
