[one-users] Openvswitch GRE

[Ruben S. Montero]

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
