Re: Openflow on XEN
Hi,
First, check the routes on each bridge, it is recommended to put data
and control in a different subnets, then check how virtual interfaces
are connected, by default each VM will have a virtual interface
connected to each bridge, so if you use xenbr0 for control be sure to
use eth1 (which is connected to xenbr1) on each VM for data traffic.
Hope that helps,
Ibrahim

Subject: Re: [openflow-discuss] Openflow on XEN
Hi All,
using XCP (Xen Cloud Platform) which comes with openvswitch - I was able to start 2 VM's and configure the openvswitch to speak to nox. I didn't need to uninstall the default bridge etc. just executed the commands ovs-vsctl set-controller /
Only issue is both the outbound traffic from VM's and control traffic to NOX goes on same eth0 (xenbr0).
Ideally, I would like to use eth0 (xenbr0) for openflow control traffic and eth1(xenbr1) connected directly to an software based openflow switch to send/recv vm's traffic. But, this is not working.
Thanks a lot for your help.
Regards,
Vishal
(p.s., not really a NOX question, but just cross posting if someone has already solved openvswitch configuration for openflow on xen or xen cloud platform)

After installing XEN and few VM's running, I have following interfaces:
xenbr0, vif1.0...., and virbr0.
Now, I can compile openvswitch from tar ball. From what I understand, I can replace - the xen bridge with openvswitch bridge ? but I am not sure, if that allows me to enable openflow ?
Basically, I want to know - what is the next step to do after compiling openvswitch ? I am able to run openvswitch with nox on linux with multiple physical ports.
Thanks a lot,
Vishal

obviously is incumbent upon you to provide OVS yourself.
