Setup KVM virtio NIC on F9

[bjrosen]

I have a CentOS5 KVM setup on F9. How do I setup a Virtio NIC? The KVM Wiki is for Debian and it talks about editing the /etc/initramfs-tools/modules file which doesn't seem to exist in either the host or the guest. It also doesn;t say if this is a host or guest file.

Would someone please give a step by step procedure for setting up a virtio NIC.

Thanks

p.s. here is the LVM Wiki
