Hello,

We need a VM so that we can be root and create and mount file systems,
right?

That=E2=80=99s a good reason to use a VM.  :-)

What about making /tmp in the VM a 9p mount of /tmp outside the VM?
That way this would be transparent, and no need to fiddle with the VM
disk sizes.

WDYT?

Thanks,
Ludo=E2=80=99.
