Is there a standard idiom most folks use to ask the
question: Am I a linux that was just booted under Xen?
 
If there is a nice guaranteed way of detecting a Paravirtualized domU 
(or if the machine is acting as a dom0), I would also be interested in 
knowing (basing it off strings in the kernel name isn't necessarily 
100% guaranteed).
 
What RH did :
"if [ -e /proc/xen/xsd_kva -o ! -d /proc/xen ]; then"
First part detects a xen dom0, second part detects a native Linux.
To detect domU, you could put the code in the "else" part, or invert the 
test, e.g. 
"if [ -d /proc/xen -a ! -e /proc/xen/xsd_kva ]; then"
