With the cache=writeback in a Lucid+KVM+libvirt+WindowXP guest setup I've experienced near host-level I/O performance in the guest. Thus this makes use of a virtio driver unnecessary.

Btw. for casual libvirt users ... adding the cache=writeback option means:
1. stop the VM (in case it's running)
2. execute "virsh edit guestdomain" on the host OS (where "guestdomain" should be the name of your guest domain)
3. edit the domain XML by adding a <driver cache='writeback'/> element under the <disk ... device='disk'>...</disk> element
