Hi, I am trying to create a gre tunnel between ovs (v1.1.0) and a linux machine which is running in a VM. I have created dp0 and attached normal eth interfaces to it. Dp0 is controlled by NOX. This far everything works fine. Now I'd like to create a gre tunnel and attach it to dp0 similar way as eth interfaces. I tried to follow the instructions from http://www.mail-archive.com/discuss@openvswitch.org/msg00495.html . However, the result from the first step is:
root@ovs:~# ovs-vsctl create Interface name=gre0 type=gre options:remote_ip=192.168.4.1 options:key=1 Jan 13 16:39:31|00002|vsctl|WARN|applying "create" command to table Interface without --id option will have no effect 5fff7494-0edd-49b2-8064-c57d095c01e5 All the examples I am able to find seems to succeed without any -id option. What am I missing here? Do I need -id option? If yes, where can I find it? Some examples use also ovs-vsctl -add-port br0 gre0 -set Interface gre0 type=gre options:remote_ip=1.2.3.4. This command does not accept dp0 (only br0) so I failed with this one too. What is the relation between dp0 (kernel concept?) and br0? Do you have any ideas what is wrong and what should I try next? Thanks a lot for your help, Johanna
