Re: PV drivers in HVM DomU

Still a Xen newb but by my understanding, when I run a guest under Xen

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.
We don't currently have any PV drivers that run on an HVM guest, though
I've heard some rumblings that someone or other might begin work on
them. As far as support for multiple cores, NetBSD 6.0 will have
support for MP on a fully-PV kernel. (A kernel built from the
cherry-xenmp branch runs, but there are a few more bugs to work out
before it lands in current)
