Hello, I've installed Hyper-V computing for OpenStack Liberty and everything went fine until I try to start an instance into Hyper-V computing node. Nova fails with exception - "PortBindingFailed: Binding failed for port fbe2d7c4-4465-4149-b235-23c213b245d0, please check neutron logs for more information" - but Neutron log can't tell much about what the problem is.

I'm running Windows 2012 Datacenter and followed this guide with the MSI.

Compute node Nova Agent Log
Compute node Neutron Agent Log

Compute node Nova config
Compute node Neutron config

Manager neutron ml2 plugin config


Solved by putting tenantnetworktypes = vlan,vxlan in /etc/neutron/plugin.ini.

Thanks in advance,

Lucas Ces

Hello Lucas.

Hyper-V currently only supports flat, VLAN and NVGRE network_types at the moment. If you wish to use VXLAN and GRE network types, you can use the neutron-ovs-agent for Windows instead of neutron-hyperv-agent. Here is the installer for the OVS for Windows:

Let us know if you have any other questions!

Best regards, Claudiu Belu
