Can anyone help to confirm that the GRE Tunneling can be used with Quantum on my RHEL6.3? My Redhat kernel version is 2.6.32-279.el6.x86_64, and the OpenVSwitch version is 1.4.2. From the wiki page( http://wiki.openstack.org/ConfigureOpenvswitch) , I find some modules are still not available in RHEL. If I want to use the GRE Tunneling, need I upgrade my linux kernel or OpenVSwitch? Thanks! -------------------------------------------------- Best regard, David Geng -------------------------------------------------- -------------- next part -------------- An HTML attachment was scrubbed...
