Hello, Great work! I was trying to native emulation example on AWS EC2. 

~$ uname -a

gtk initialization failed

I was hoping this would work (and then SSH/console), but I think I don't understand 'lite' and the need for gtk. I suspect this is even the wrong forum to ask, any tip appreciated.

I got it, of course, after reading the qemu help :). Thanks for listening.
