It is highly recommended to use the virtio devices whenever you can, as they
provide a big performance improvement. Using the virtio generic disk controller
versus an emulated IDE controller will double the sequential write throughput,
as measured with `bonnie++(8)`. Using the virtio network interface can deliver
up to three times the throughput of an emulated Intel E1000 network card, as
measured with `iperf(1)`. footnote:[See this benchmark on the KVM wiki
