I'm using kolla-ansible rocky branch with source containers to deploy openstack. I'm running the controller as a vm on top of my hyper-v compute host. I have a vlan subnet created but the vm's nic does not get attached to a switch. I'm using windows 2016 server on the hyper-v side.

This is the relevent log from my hyperv-neutron agent.

I read a bit and some suggest this is because the neutron-server does not have the networking-hyperv package. Well mine does and it's version 5.0.0 but the package on my hyperv server is 7.0.1.0rc1. I used this installer to install the openstack hyperv bits https://cloudbase.it/downloads/HyperV...Rocky1803.msi

Here are the neutron server logs in debug mode

Hi,

Make sure to also enable the hyperv ml2 plugin as described here: https://compute-hyperv.readthedocs.io...

Now that I think of it, we'll probably want to move that section to the "prerequisites" page.

Regards, Lucian

My ml2_conf.ini has hyperv enabled and the networking-hyperv package is installed on the neutron-server. VM still does not get a hyper-v switch set.

I suggest enabling debug mode for the neutron services (hyper-v as well as neutron server) and check the logs. You may search by port id, most probably this will get us to the cause of the port binding failures.

I have attached the relevant logs. Thanks for your help.

Thanks for the logs, those helped me find the issue. I sent a fix and by next week we should have updated MSIs as well as a new networking-hyperv package that you may install manually. To be honest, we've been mostly focusing on the OVS neutron agent and this issue has somehow slipped.

Thanks, I'll explore the OVS agent until then.
