Ryu in the context of Fedora

[Kyle Mestery (kmestery)]

Robyn asked me to send something out to the cloud sig around Ryu. For those unfamiliar, check it out here:

And the Fedora wiki entry for it here:

http://fedoraproject.org/wiki/Features/Ryu

Ryu is itself labeled as a "Network Operating System". It is effectively a Controller which can control Open vSwitch instances on the host, in addition to being able to control other devices speaking OpenFlow (e.g. switches which support OpenFlow). Ryu allows you to write applications on top of it as well. A simple application included is a simple L2 learning switch. There is also integration with OpenStack Networking (the project formerly known as Quantum) via a plugin.

Now, in the context of Fedora, I've been using Fedora+Ryu as one of my main OpenStack development environments, and from what I can tell, because Fedora doesn't use the upstream Open vSwitch kernel module and loses things like patch ports. I'm wondering if others have seen this issue on Fedora? I have not opened a bug on this yet, but can do that soon. I suspect the OpenStack Networking gerrit review listed below may make this work again, as it uses veth ports instead of OVS patch-ports to connect OVS bridges:

Robyn, please chime in and let me know if there is anything else in the context of Ryu that you'd like to discuss.

Thanks,
Kyle
