commit b80c245ba529ab603910b5c0e2fa466bf0b6a146 Author: Claudiu Belu <cb...@cloudbasesolutions.com> Date: Sat Jan 13 17:58:56 2018 -0800 hyper-v: Logs tips on PortBindingFailed When spawning an Hyper-V instance with NICs having the vif_type "hyperv", neutron will fail to bind the port to the Hyper-V host if the neutron server doesn't have the "hyperv" mechanism driver installed and configured, resulting in a PortBindingFailed exception on the nova-compute side. When this exception is encountered, the logs will say to check the neutron-server logs, but the problem and its solution are not obvious or clear, resulting in plenty of questions / reports, all having the same solution: is there an L2 agent on the host alive and reporting to neutron, and if neutron Hyper-V agent is used, make sure to install networking-hyperv and configure neutron-server to use the "hyperv" mechanism_driver.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1744032 Title: Hyper-V: log warning on PortBindingFailed exception Status in OpenStack Compute (nova): Fix Released Bug description: Description =========== When spawning an Hyper-V instance with NICs having the vif_type "hyperv", neutron will fail to bind the port to the Hyper-V host if the neutron server doesn't have the "hyperv" mechanism driver installed and configured, resulting in a PortBindingFailed exception on the nova-compute side. When this exception is encountered, the logs will say to check the neutron-server logs, but the problem and its solution are not obvious or clear, resulting in plenty of questions / reports, all having the same solution: install networking-hyperv and configure neutron-server to use the "hyperv" mechanism_driver. Steps to reproduce ================== 1. Do not configure neutron-server with a "hyperv" mechanism_driver. 2. Spawn an instance having NICs with the vif_type "hyperv". Expected result =============== PortBindingFailed, and a clear explanation and / or solution for it. After the execution of the steps above, what should have happened if the issue wasn't present? Actual result ============= PortBindingFailed, telling users to check the neutron-server logs, which doesn't contain the obvious problem / solution. Environment =========== Hyper-V compute nodes, with neutron-hyperv-agent agent. Any OpenStack version. Logs & Configs ============== Logs: http://paste.openstack.org/show/646888/ To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1744032/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
