Hi,
I'm trying to get instances in a Hyper-V compute node to communicate with instances on other hypervisors using Open vSwitch and neutron-ova-agent over VXLAN. My other hypervisors run CentOS/KVM. Instances on the Linux machines can communicate just fine, but I don't get the ones running in Hyper-V to communicate.
The setup runs two controller nodes (10.60.11.21 and 10.60.11.22 with a shared VIP 10.60.11.201) with the L3-agent running the router on .21. In addition I have two separate hypervisors installed, one CentOS/KVM (10.60.11.23) and one Windows Server 2016 Datacenter/Hyper-V (10.60.11.25).
The Hyper-V host runs 3 VMs, one CirrOS (192.168.0.7) and two Windows Server (one with 192.168.0.12 and one trying to use DHCP).
I have created a Hyper-V VMswitch named "br-ex" and enabled the Open vSwitch extension. The VMswitch is connected to an interface named "Tenant" (without IP). I have also manually created a Open vSwitch bridge named "br-ex" and connected the "Tenant" port above to it. The hypervisor also has a Management interface with IP (i.e. 10.60.11.25) with connectivity to the other Openstack nodes.
The VMs on Hyper-V can ping themselves and other VMs on the same Hyper-V host. They can not access the router, DHCP-server on the controller node or VMs on other hypervisors.
I think the problem has something to do with that Open vSwitch does not open a listening socket for VXLAN (udp/4789), i.e. according to netstat -na | find "4789".
If I try to connect to an instance from the outside (10.20.150.115) I see the incoming TCP SYN on the Hyper-V host.

I.e. the NAT/routing into Hyper-V works. But the VXLAN port is not open, so Hyper-V-host responds with ICMP Port Unreachable.

Firewalls in both the hypervisor and VMs are turned off.
