Hi,

Thanks for the patch! - I couldn't apply it automatically (not entirely 
sure what to do with a git diff like that :) - and, the hvm.c part of patch 
wouldn't apply cleanly anyway (too much difference).

*Having said that* - I applied it by hand to my 10.1-R system, and it seems 
to work perfectly. I've put the XENHVM and xenpci back in the kernel, 
re-enabled veridian for that VM, and put 'hw.xen.disable_pv_nics=1' in boot 
loader.

I now have a PV disk, but HVM NIC (re0) based machine - that's agile, and 
works with OpenVPN and inter-VM routing.

I can post the standard 'diff -u' patchset against 10.1 back to the list if 
needed (I know other people had PV NIC issues and were using the same 
non-agile "boot as HVM" fix for it).

Cheers,

-Karl
