I'm just setting up another less critical system to reproduce it. To 
confirm, I just take GENERIC and remove 'XENHVM' and 'xenpci', and it 
should boot without PV.

I'll post the results / panic & exact versions when I get it (though some 
goes off the top of the console = could be interesting).

Can you technically have a system that has HVM network (i.e. realtek) but 
still has disk PV, and/or is agile? (i.e. can run xen-tools)?

That'd kind of be a 'perfect' workaround for all our network woes (openvpn, 
routing etc.) at the moment - even if the performance of HVM re0 isn't as 
good as a PV xn0
