Hi, I have some questions on the different VM states.


1. I tried to redraw the state diagram and adding an additional state, representing a VM that has been killed by the console command vm destroy.


Is this correct? (hint: inline img following for all the text/plain readers ;-) )


2. What exactly is the Unknown state? Are there any state changes (and api calls) to recover an VM in the Unknown state – eg. into the halted state?


3. And what happens to a VM that gets hit by the VM.destroy? Is this VM completely deleted from the known space of the xend? So afterwards there is no way to re-create it without the config?


4. What commands does the console command vm destroy exactly do? Does he destroy the machine or just put it into the halted mode?
