Hyperv nova compute drivers installation

edit

Hello,

It would help a lot if logs were also included, specifically the C:\OpenStack\Logs\nova-compute.log and C:\OpenStack\Logs\neutron-hyperv-agent.log files, as too little information is given by just the horizon error message.

Keep in mind that Neutron Hyper-V Agent doesn't support VXLAN networks. Are your networks using VXLAN by any chance? If you do have VXLAN networks and desire to use them, you should use Windows OVS + neutron-ovs-agent. https://cloudbase.it/openvswitch/

My other guess is that the instance failed to spawn because the neutron port couldn't be bound to the Hyper-V host. This happens if you didn't configure your Neutron controller to also use the Hyper-V ML2 mechanism driver.

For this, you will have to edit the file /etc/neutron/plugins/ml2/ml2_conf.ini and have the configuration option in the [ml2] section:

mechanism_drivers = openvswitch,hyperv

Any other mechanism drivers can be added to that list, but it is important that those 2 are there. After the file was edited, the neutron-server service will have to be restarted. Then, you can try spawning a new instance.

Best regards,
