+## Create a disk image file

+Xhyve will use a file as a logical disk. Be sure you have the filesize you need, because growing the file later is tricky to impossible (you could try to use `qcow` or similar to get around this, but qcow volumes can be tricky to mount).

You probably want to use the [mini.iso](http://archive.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64/current/images/netboot/mini.iso).
