Hi, All!

I found a bug! When I start the default network, I got a error shown as below:

[root@localhost ~]# virsh net-start default error: Failed to start network default error: error creating bridge interface virbr0: Operation not supported

I think it's caused by commit fc7b23db (released in 1.2.14). For some reason, older kernels do not know how to create a bridge via netlink. I wonder if we should workaround it somehow. Michal
