Claudiu Belu e2d08409f1 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"

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:


For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
