But keep in mind that the "fork-vm" command even with this update
would still not produce for you a "fully functional" VM on its own.
The user still has to produce a new VM config file, create the new
disk, save the QEMU state, etc.

 If you fork then the configuration should be very similar. Right?

So why does the user requires to provide a new config rather than the command to update the existing one? To me, it feels this is a call to make mistake when forking.

How is the new config different from the original VM?

As a side note, I can't see any patch adding documentation.
