It doesn't work.
But that has nothing to do with your patch!

It seems like I have something destroyed with my fiddeling around on lxc. If i try to create a container. It there is the information that the container is running the setup, but after that the container wich was initially shown vanishes and that's it. (No matter if I use the original deamon.py or yours) So I have first to look what I have borked on my system.

I'm grateful for tipps. I have already deinstalled lxc many times and have searched for directories with the name lxc on my file system to empty them. Unfortunately with no success regarding the container setup. I have to dig deeper I fear....
