PV drivers in HVM DomU

[David Howland <metalliqaz%fastmail.fm@localhost>]

Still a Xen newb but by my understanding, when I run a guest under Xen 
HVM, I can increase performance dramatically by using PV "drivers" to 
access network and disk (thus avoiding QEMU emulated devices).  This is 
usually recommended in Windows, for example.

So, is it possible or advisable to try and compile xenbus, xennet, and 
xbd into a GENERIC kernel?

I am running GENERIC under HVM right now so I can use all four cores.

thanks,
