Open Stack

I have a cloud that is using vxlan's over infiniband. Its working great.

Now, I have a second system, a Lustre cluster that I would like to make available to a tenant in the cloud. I can't bridge into this network since its IB. Routing onto it is also proving to be tricky...

One idea I had was to allocate a local link pair on each Lustre node, install neutron-openvswitch, configure it the same as a compute node, then add one end of the local link to the tun-int the same way as Nova would. This would make the remaining link pair talk over the vxlan.

One snag though, while it does work, it does so only if I launch a Nova instance on the Lustre node first so it gets the flow rules setup.

Would it be difficult to write a little script, that creates a vif pair, just like Nova would and ensure all the flow rules were hooked up right?

Thanks,
Kevin
