Directly, here is the issue I meet.

I start a all-in-one openstack Folsom with Quantum network( using linux
bridge plugin)

   - First I can not ping outside of the host. Following is the network
   setting. I think this should be work. But I can ping 10.10.0.1(gate way) in
   the host
   - Second, what's the usage for ns-1c37cab7-6b qg-82fef397-e1
   qg-82fef397-e1, they are attached on nothing bridge.

eth0: public Ethernet 10.10.0.0/24
eth1: private Ethernet 192.168.101.0/24
eth2: manage Ethernet 10.12.0.0/24


[root@all-in-one ~]# brctl show
