Ok, I managed to fix it. I needed to load the tun module to get it 
working. Maybe this should be added as a check in runqemu?

I am now having issues with connecting to the live image, I recieve a 
connection refused message when I try to upload the file to the virtual 
machine, I have just the stick minimal-dev image so no additional 
passwords set.
