Hello

Thanks for reply.

I have something like this.
root at ovs2:/var/run/openvswitch# ls
br2.mgmt   db.sock                ovsdb-server.pid
 ovs-monitor-ipsec.pid  ovs-vswitchd.pid
br2.snoop  ovsdb-server.1377.ctl  ovs-monitor-ipsec.1306.ctl
 ovs-vswitchd.1386.ctl
root at ovs2:/var/run/openvswitch#


I dont know why there is multiple instance is running. I just loaded the
disc image "https://www.utahddc.geniracks.net/image_metadata.
php?uuid=468c846d-5395-11e3-880c-000000000000" and ssh into it.

After that added a bridge then the error message. I am new to this OVS.
Could you please tell me is this is the problem with image or my approach ?
I got the same error message  when i build OVS from scratch using steps in
http://groups.geni.net/geni/wiki/HowTo/InstallOVSInProtoGENI. ( Last step
fails).

The above disc image is also behaving in the same way .

Could you pls help me.

Thanks
Navaz
