Hi Justin, unfortunately I can't install the switch in the hypervisor, I can just use the VMs.
I'm starting from scratch before the installation of Openstack. First of all I want to setup the SDN network. The connection between the switch and the ODL Controller works, I can see OF packeIn and packetOut with tcpdump on the controller interface. Now the problem is to connect the OVS inside vm5 to the other VMs. In vm3 and vm4 I have assigned an IP address to the interface eth1. (respectively 10.0.0.3 and 10.0.0.4) Than I have done: ovs-vsctl add-br br-eth1 ovs-vsctl add-port br-eth1 eth1 In vm5 , so where I've installed OVS, I've done: ovs-vsctl add-br br ovs-vsctl add-port br eth1 -- set interface eth1 type=gre options:remote_ip=10.0.0.3 ovs-vsctl add-port br eth2 -- set interface eth2 type=gre options:remote_ip=10.0.0.4 But I think I still missing something because the traffic does not go through the switch. Any suggestion to go forward? Ho to create the "physical" link? Thanks. Silvia P.S. If could be usefull: I'm considering eth0 as management network. In vm3 and vm4 there are also eth1 and eth2 for both VMs. In vm5 there are also eth1 eth2 eth3 and the openflow bridge/interface that I've created to set the Controller. 2015-05-26 22:17 GMT+02:00 Justin Pettit <jpet...@nicira.com>: > > > On May 26, 2015, at 3:11 AM, Silvia Fichera <fichera....@gmail.com> > wrote: > > > > Hi all, > > maybe mine is a silly question but it's getting me crazy! > > My university gave me five VMs in a server to make some experiments with > OpenStack+OpendayLight. > > So I have: > > vm1 -> ODL Controller > > vm2 -> OpenStack Controller > > vm3 / vm4 -> Compute nodes > > vm5 -> OVS > > > > TO configure my environment I've followed the ODL's wiki about VTN, but > I still do not understand how to attach the VMs that represent the compute > nodes to the switch. > > I have already set the Controller ODL (in fact with 'sudo ovs-vsctl > get-controller bridge' I can see the IP address and the port of my > controller).
