Re: Grizzly GRE tunneling network set up problems

I followed instructions in
http://n40lab.wordpress.com/2013/06/03/centos-6-4-openvswitch-installation/
on my compute node as a test. Restarted OVS, but still see the same
error in the ovs-vswitchd.log. This is what I have

anything else I need to check? Does above looks right to you?

Thanks
