Hello,
I'm having trouble setting up Grizzly Quantum with Openvswitch using
GRE tunnels.
The basic problem is that Quantum errors out when configuring the tunnel:
2013-08-07 10:14:36 INFO

The first thing to note is that I have manually setup tunneling
between my Quantum server and the compute node. GRE tunneling works
fine, so that is not the issue.
The strange part is that Quantum doesn't appear to be initializing
br-int and br-tun on either server. Quantum should be setting up the
patch interfaces, but they are missing.
[root@quantum ~]# ovs-vsctl show

Besides the configurations below, the only configuration that I did was
both servers
* ovs-vsctl add-br br-tun
* ovs-vsctl add-br br-int
on Quantum
* ovs-vsctl add-br br-ex
* ovs-vsctl add-port br-ex ens8.25
Here are my configurations:

Could someone help me figure out what is happening?
Thanks,
Justin
