Hi ,

We are following RHEL openstack guide for liberty release. We arr not able to start an instance and getting couple of errors in nova and compute log files. One of those errors is "ortBindingFailed: Binding failed for port 41151c02-9e02-49f7-8101-226c2bb3c1a6, please check neutron logs for more information.ortBindingFailed" in nova-compute log.

We are using private(self provider) network ,not plublic.

Please help us to solve this issue.

Hi, could you please post a link to the guide that you are following? Are you using Hyper-V compute nodes?

In order to bind Neutron ports on Hyper-V, make sure you have networking-hyperv installed on your Neutron controller node (for liberty, use 1.0.4: pip install networking-hyperv==1.0.4). Afterwards, make sure to configure your Neutron server to use the hyperv mechanism_driver, by adding it to the mechanism_drivers config option in /etc/neutron/plugins/ml2/ml2_conf.ini. You should have something like: mechanism_drivers=openvswitch,hyperv. You can have any other mechanism drivers in the list.

For more details and more help in setting up and debugging any networking issues, please follow the article:


Best regards,

For generic OpenStack related questions I'd recommend:
