[neutron][hyperv] Neutron Hyper-V agent - unable to bind port


Hello, I am relatively new to Openstack, and am not sure if
support-type questions are welcome here, but if they are, any help
would be greatly appreciated!


I have a fully working system running Rocky that I built using
Openstack-Ansible on Ubuntu 18.04.
I am using it as a POC to test out for use in my datacenter, which has
a large Hyper-V investment.

I am using the ML2 Linuxbridge agent with my KVM hosts, with VLAN,
VXLAN, and FLAT networking all working great.

While attempting to add some Hyper-V nodes into the mix, all is
working fine, I can provision new Instances from image,
Cinder volumes mount via iSCSI, and they boot up successfully. The
issue is that the Hyper-V virtual switch remains in
a disconnected state, and does not tag a VLAN when it should.
The port state also shows as "down" in the Horizon Web UI or from the
Command line.

On my neutron server containers, I have installed the
"networking-hyperv" driver.
My /etc/neutron/plugins/ml2/ml2_conf.ini file has the following:

[ml2]
extension_drivers = port_security,qos
mechanism_drivers = linuxbridge,hyperv
tenant_network_types = vxlan,flat,vlan
type_drivers = flat,vlan,vxlan,local

Neutron Server Container Logs: ( I think the key line is: Device
fbb9010c-3326-4689-b46c-c3393e43f23b has no active binding in host
None )

If I happen to "catch" the VM in the Hyper-V console while it's being
provisioned, I can attach the vNIC to the Hyper-V Switch, and check
the box and tag the VLAN and the system will get an IP from the DHCP
Agent, Pull its hostname and ssh key from the Metadata Agent, and
everything else - although Openstack will still have the port status
as "Down"

There's not a lot of info out there on specific nuances of Nova with
Hyper-V, If I need to look into the Open vSwitch Agent, I'm not
opposed to going that direction either.
I also realize that I may need to reach out to Cloudbase directly for
better support.

Thanks for your consideration and support!
