Hello everybody,

I have a setup with OpenStack Kilo with the following nodes:

• "controller" (Controller Node)
• "odl-controller" (OpenDayLight Node)
• "compute2" (one compute node)
• "compute3" (another compute node)
• "network" (network node)

All of them run Ubuntu 14.04 LTS with default OpenStack installation + default OpenDayLight Installation. I followed the wiki and everything went smooth. Then I createad a VM on compute2 and another VM on compute3. Then, I went into compute2 console and I typed:

ovs-vsctl show

and the result is

root@compute2:~# ovs-vsctl show
21624d5f-499c-487a-b7c5-90ef48c3d9e5
    Manager "tcp:10.0.0.91:6633"
    Bridge br-int
        Controller "tcp:10.0.0.91:6633"
            is_connected: true
        fail_mode: secure
        Port br-int
            Interface br-int
        Port "tap91e68e7c-75"
            Interface "tap91e68e7c-75"
    ovs_version: "2.3.2"

Now I am wondering: why there is "br-int" bridge only ? I was supposing to find also "br-tun" or at least another bridge. Is this normal ? What am I doing wrong ?
