Description

We need to provide examples for configuring libvirt, since we now support SCSI. Virtio and SCSI should be the main examples. We should avoid IDE since it's slow.

This strictly speaking isn't true "Note that this uses the IDE driver. The virtio driver does not support discard." probably should be more like this "Note that this uses the IDE driver. The virtio-blk driver does not support discard; however, the virtio-scsi driver does support discard."
