I just added that to prevent over-motivated hackers to run untested code ;-)

The questions is how to implement that cleanly?

We use normal 'vdisks' to store state - I allocate the with vdisk_alloc().

Qemu can use those disk for drives, so it must be possible to use them to store
state. I will do more test.
