Hello I am trying to install nova compute drivers on Windows Server 2012R2 and when the install finishes I am able to see the hyperv as a hypervisor on the openstack dashboard, but when i want to lauch an instance i get an error that no suitable hosts were found. I have OpenStack Mitaka installed on my lab and its working fine with KVM hypervisors but i wanted to mix it with hyperv as well. My hyperv machine has 2 NIC. First NIC is the management interface and it has a local ip which is in the same range with the openstack controller machine. Second NIC i added it to a hyperv bridge which is created from the installer and it doesn't have an IP address, but its connected to the switch where i get my public IP range for the VM's. During installation i provide all the correct information that it requires, but in the end i cannot get it to work. If someone could give me instructions on how to install the nova compute drivers properly it would be great. Thank You.

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,
