Check your neutron server status and logs for any errors or python traces. Possibly you made something wrong because it seems neutron is not working properly if you can not retrieve objects in dashboard.

2016-12-22 18:51:10 +0200 commented answer Cannot launch instance on hyper-v compute node

After compute driver installation you need to configure you neutron server to work with native hyperv switch. Please look through this article: You need to configure neutron ml2 plugin with hyperv mechanism driver.

Well, you have Neutron server with linuxbridges, it's okay. How did you prepare compute nodes to connect to Neutron networks? Did you install hyperv neutron agent? Did you configure neutron mech driver on neutron server for hyperv networking?

2016-12-22 15:50:30 +0200 answered a question Cannot launch instance on hyper-v compute node

Hi, what kind of networking do you use in Hyper-V compute nodes? Native hyper-v switch or OVS extension?

Hi, When I try to live migrate an instance, it goes to another host successfully, but in nova-compute.log I see: Exception during cluster live migration of instance-0000027d to bc12: <x_wmi: generic="" failure="" &gt;="" what="" can="" it="" be?<="" p="">

I use Mitaka Release and OVS 2.5.1

Hi, Alin. Thanks. Wait you update.

2016-12-12 15:00:21 +0200 commented answer OVS 2.5.1 Tunnel Problem, No Network inside VM

Hi, Alin. Solution is to add some configuration options to agent section. of_interface = ovs-ofctl ovsdb_interface = vsctl There is another problem with lost interface TAG in OVS after Live Migration.

Problem closed. Found solution.

2016-12-10 21:16:26 +0200 asked a question OVS 2.5.1 Tunnel Problem, No Network inside VM

Hello, After updating OVS to 2.5.1 no vxlan tunnels can't be created automaticaly within br-tun. To check we can remove all VM from host so OVS will have no tunnels to the other agents. Then we create a new VM and OVS tells failed to query port : Invalid argument when tries to get tunnels. I'm using OVS 2.5 on neutron server.

I'd be more than happy if you can help me with this issue.

2016-11-21 10:55:53 +0200 asked a question Hyper-V Live Migration doesn't work

Hi Team, I'm using Mitaka cluster driver with OVS 2.5. When I perform live migration, an instance loses network connection but succesfully goes to another hosts. There was a bug in Liberty where ovs port had not been migrated to target hosts but now it is seems to be okay, ovs port is on target host but add with errors.

vswitchd.log (migration time)

nova-compute.log (migration time)



If I execute the command (ovs-vsctl --timeout=120 -- --if-exists del-port 4b26fd63-e779-49c9-b419-ac2c53ef8c9a ....) logged in nova manually then I get network connection even without restarting the services.

I've also logged OVS debug rpc (another migration) and it contains "protocols":"OpenFlow10","datapath_version":"<unknown>"}

Please, help to investigate it, as our team is implementing cloudbase solution. I'm ready to provide all logs.

Is there any nova.virt.hyperv.cluster.driver.HyperVClusterDriver release for Openstack Liberty? Is it possible to adapt mitaka driver for liberty release?
