Build a virtual machine that contains the operating system declared in
@var{file}, and return a script to run that virtual machine (VM).
-Arguments given to the script are passed to QEMU.
+Arguments given to the script are passed to QEMU as in the example

The VM shares its store with the host system.
Thanks,
