Joon,

I just checked with the person who set up that Liva (and several others) and he said he didn't have to do anything in particular as far as booting goes. But, he has had mixed experiences where some will boot headlessly, while others won't. Seems a bit mysterious. 

He did say that sometimes hooking a keyboard/monitor up, then booting, and 
then trying again, it may start working. So, you could try a few more times 
and see that gets you anywhere. We're definitely seeing mixed results on this 
issue.
