Open Stack

Hello,

>From what I can see in the trace you included, it seems to be either Kilo or master (it uses networking-hyperv, which was introduced in Kilo).

Also, it might be useful to know if you are using Windows Server 2012 or Windows Server 2012 R2. Running this in Powershell should yield the OS version:

[environment]::OSVersion.Version

6.2 is Windows Server 2012
6.3 is Windows Server 2012 R2

As for port binding, neutron-hyperv-agent, if it fails to bind a port, it will retry to bind it. Which means that even if you see that trace, it doesn't mean that the binding failed at all. If you run "Get-VM | Get-VMNetworkAdapter" in Powershell, you can see that ports have been bound to the vSwitch.


Also, I don't know if your environment has been properly configured, but I can tell that you have set the "hyperv" Mechanism Driver on your Controller node in the /etc/neutron/plugins/ml2/ml2_conf.ini and you are using a network type compatible with Hyper-V. Otherwise, neutron would flag the port with something like "port binding failed" and neutron-hyperv-agent wouldn't attempt to bind it.

A good start would be taking a look at: http://www.cloudbase.it/quantum-hyper-v-plugin/
The linked page contains all the configuration you would need plus some troubleshooting steps that can help.

Also, as Alessandro said, copies of C:\OpenStack\Log\nova-compute.log and C:\OpenStack\Log\neutron_hyperv_agent.log and the neutron server's neutron.conf file can be useful. 
Also, setting debug=True in the Hyper-V's neutron_hyperv_agent.conf can be useful until the issue has been solved.

[DEFAULT]
debug = True

Let us know how it goes.

Best regards,
Claudiu Belu

Hi Lily,

What version are you running, Icehouse, Juno, Kilo or master?

A full copy of the nova-compute.log and neutron_hyperv_agent.log on a pastebin
might be helpful. Additionally, your neutron.conf from the neutron server could
help along with your neutron network configuration.

Finally, the output of "Get-VMSwitch" on the Hyper-V node could provide some
insight on your visrtual switch configuration.

This question is deployment related and at this stage not a development topic,
so IMO a more suitable location to continue the discussion would be:
https://ask.openstack.org

Thanks,

Alessandro

I created a vswitch on the second one and use it to connect to instances. Below is my neutron_hyper_agent.conf:
