 * `device` - Name of the device node the disk image will have in the VM, e.g. *vdb*. If unspecified, the next available device is chosen.
 * `size` - Size of the disk image. If unspecified, defaults to 10G.
 * `type` - Type of disk image to create. Defaults to *qcow2*.
+* `bus` - Type of bus to connect device to. Defaults to *virtio*.
