Re: determining if kernel is dom0 kernel or not.

[Keir Fraser <keir@xensource.com>]

If you are looking for running on Xen versus not on Xen (rather than dom0
versus domU), and you are interested in x86 only, then the program in
tools/misc/xen-detect.c is along the lines of what you want (and can be cut
down to size if you just want e.g., a non-zero return code if running on
Xen).

If you want to detect dom0 specifically then that's trickier --
/proc/xen/privcmd for example exists even in a domU, if the kernel is
dom0-capable. You'd have to be root and then try a privileged hypercall. :-)
