Hi Ricardo, I do not have any expirience myself configuring a GRE port in openvswitch. I went through the documentation and it seems that it should not be very different from setting VLAN port.
>From an opennebula stand point, you may need to configure the GRE tunnels as part of the host configuration. Once the tunnels are set up between the hosts you need to add the VM interfaces, this is done by the hypervisor. So, let say that bridge br1 is the gateway with the GRE tunnel. You may simply need to define the network with BRIDGE=br0 and dummy network drivers. If you need to do some management operations on the bridges you may hook on the pre/post scripts . Hope it helps Cheers Ruben On Thu, Sep 20, 2012 at 10:46 AM, Sándor Guba <[email protected]> wrote: > HI. > > In my opinion VLAN tagged network is (still) supported better in > OpenNebula.
