Public bug reported: I'm attempting to demo/use LXC backend for nova in EC2, all on a single system. When doing so, I get the trace below. It appears that we can get further by doing: $ sudo brctl addbr br0 $ sudo ifconfig br0 up $ sudo vconfig add br0 100
However, doing so just gets us further along to fail at bug 812553.
