[TriLUG] Xen applications

[Michael Hrivnak]

Ah, for this purpose, Xen could server you well.  The compatibility issue to 
which you refer is one of the xen kernel.  Some distributions are happier 
than others about booting from the xen kernel, but I suspect you'd be able to 
make it work for most or all of those.  If you've got the time to invest, 
give it a shot.
