That is an "invalid" command. What you're trying to do is to launch a VM called "snapshot". I'm not sure if those are your intentions. But it sure as I'm writing this, this action requires a GUI, which I'm willing to bet you don't have, right?

So, please explain: 1) what you want to do, and 2) how are you setup in order to to do what you want to do.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.
Do NOT reply with the "QUOTE" button, please use the "POST REPLY", at the bottom of the form.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
