[Bug 812548] Re: bridge not set up correctly with LXC and all-in-one system

[Scott Moser]

** Description changed:

  I'm attempting to demo/use LXC backend for nova in EC2, all on a single system.
- When doing so, I get the following trace:
+ 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.
+ 
+ Trace from nova-compute.log:
