> Yesterday I encountered "bridge module is loaded, not loading brcompat" error (http://openvswitch.org/pipermail/discuss/2012-November/008446.html), and I solved it by not setting a "bridge_port eth0" in /etc/network/interfaces. Here's the file now:
>  
> ----
> auto eth0
> iface eth0 inet static
> address 0.0.0.0
>  
>  
> auto br0
> iface br0 inet dhcp
>  
>  
> ## bridge_port eth0 ## removed this
>  
>  
>  
> auto virbr0
> iface virbr0 inet dhcp
>  
>  
> ----

> and this is `ovs-vsctl show`:
> ----
> Bridge "virbr0"
> Port "virbr0"
> Interface "virbr0"
> type: internal
> Port vethfFrrKy
> Interface vethfFrrKy

> Bridge "br0"
> Port "eth0"
> Interface "eth0"
> Port "br0"
> Interface "br0"
> type: internal

> It seems working well, only that the "network device configuration" time at startup is very long. I guess this is related to virbr0, the default libvirt virtual bridge, which doesn't get the configuration.

> Also you might notice that eth0 is connected to br0, and these two configurations as shown are not conform.(So first question, is there a cleaner way to configure ovs? I tried the instructions in openvswitch-switch.README.Debian, but didn't work. btw I'm using ubuntu 12.04)
>  
> And since virbr0 doesn't get enough configuration, it's isolated from the Internet. So how to make both br0 and virbr0 connect to the Internet? I think I can connect virbr0 to br0 but don't know how. And to be more generally, can I create arbitrary topologies inside ubuntu using ovs?
