Interesting and rather useful, because a user might choose a xen
kernel on a non-xen machine and wonder afterwards why his/her system
did not boot... This also does not seem too hard to implement.

I think that we can detect whether we are inside xen by checking if
/proc/xen/ and /proc/sys/xen/ exist. The same can be done for vserver
by checking if /proc/sys/kernel/vshelper exists.

What do you think of those tests? Maybe someone has better ideas,
as those are the first checks which came to my mind. :)
