-m <script>
Run a script in hypervisor context prior to starting the guest.
This is essentially the same as the shell context.
-c <code>
Run a literal string of code prior to starting the guest.
-S
Start a shell instead of directly starting the guest. Use `start` to
actually begin guest execution.
This also adds a couple example scripts under hv/.
