Re: [openstack-dev] [Ironic][Neutron] Testing of Ironic/Neutron integration on devstack

Well with the current approach in your code you would have to basically re-implement all of the logic in the openvswitch agent that sets up VXLAN tunnels and isolation of nodes on different VXLAN networks (either via flows or local VLANs). That will be quite a bit of work. We can already leverage the L2 agent’s logic if, instead of setting VLANs/VXLANs directly in your driver, we just wire up a patch port to br-int using the correct name that the L2 agent expects for the Neutron port the bare metal VM has. Then the L2 agent does its normal logic to get the traffic onto the right VLAN/VXLAN/GRE/whatever.

I didn't know you were working on an OVS driver for testing in CI as well. :) Does this work by getting the port wired into OVS so the agent recognizes it like a regular port so it can be put into VXLAN/VLAN or whatever the node is configured with? From what I can tell it looks like it's on a completely different bridge so they wouldn't have connectivity to the rest of the network. Driver works with VLAN at the moment, I don't see any reason why it wouldn't work with VXLAN. Ironic VMs are created on devstack by [0]. They are not registered in Nova/Neutron so neutron-ovs-agent doesn't know anything about them. In single node devstack you can't launch regular nova VM instances since compute_driver=ironic doesn't allow this. They would have connectivity to rest of network via 'br-int'. I have some POC code[1] for 'baremetal' support directly in the OVS agent so ports get treated just like VM ports. However, it requires upstream changes so if yours accomplishes the same thing without any upstream changes, that will be the best way to go.   In real setup neutron will plug baremetal server to specific network via ML2 driver. We should keep as much closer to real ironic use-case scenario in testing model. That is why we should have ML2 that allows us to interact with OVS.   Perhaps we can merge your approach (config via ssh) with mine (getting the 'baremetal' ports wired up for real connectivity) so we don't need upstream changes. 1. https://review.openstack.org/#/c/249265/ Cheers, Kevin Benton On Wed, Nov 25, 2015 at 7:27 AM, Vasyl Saienko <vsaie...@mirantis.com> wrote: Hello Community, As you know Ironic/Neutron integration is planned in Mitaka. And at the moment we don't have any CI that will test it. Unfortunately we can't test Ironic/Neutron integration on HW as we don't have it. So probably the best way is to develop ML2 driver that will work with OVS. At the moment we have a PoC [1] of ML2 driver that works with Cisco and OVS on linux. Also we have some patches to devstack that allows to try Ironic/Neutron integration on VM and real HW. And quick guide how to test it locally [0] https://review.openstack.org/#/c/247513/ https://review.openstack.org/#/c/248048/ https://review.openstack.org/#/c/249717/ https://review.openstack.org/#/c/248074/   I'm interested in Neutron/Ironic integration. It would be great if we have it in Mitaka.
