Hmm, looks like some issue w/ Mir, but I'm no expert in that, so I'm not 100% sure.
As a test, could you make a Ubuntu Desktop Next USB stick and try to boot from that and see if the live session works? See https://wiki.ubuntu.com/Unity8DesktopIso for more details on how to do that if you don't know already. I want to rule out the LXC stuff acting funny.
