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.

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
