doing this or something)?
That's the situation we've got already - we compile Xen and KVM to use
the rtl8139 nic since that's the best lowest-common denominator. It was
a barely passable approach so far, but with VirtIO it is now past its
sell
by date and we have to key off os type/variant. If we don't then we'll
be limiting guests to 1/100 of the their potential performance. Not cool

Yikes :)
I'll do some more manual creation tests tomorrow using the qemu
command line.
Passing in the OS version is doable as we should soon have "cobbler
import" storing that data.
Right now, it stores the name "RHEL5.2", etc, but that's not hard
enough to key off of.

Ok, so friday I tried walking through this with virt-manager and chose
the OS/variant as 2.1, and it picked the wrong network
driver there too and could not install 2.1.
