     If you're using the XEN3_DOMU kernel, then you would be running

     Where is O'Reilly, period?  They are definitely not the O'Reilly
of my youth.

     HVM uses things like wm0, sd0, etc.  PV and PVHVM uses xennet
and xbd.

     Userland doesn't change for any of the options (not counting
modules, but modules aren't strictly userland).

} 3. Will I need to make any configuration changes to things in /etc ?

     Maybe, since it isn't clear what exactly you're running.
