Hi,

We would like to use Hyper-V with OpenStack and Open vSwitch on our OpenStack Pike deployment using Cloudbase installer.

Our setup:

Windows 2012 R2
2 NICS
Teaming (bond0) with NIC1 and NIC2 using LACP
Multiple team VLAN interfaces on top of bond0 (bond0.70, bond0.73, etc...)
An IP address on each bond0.XX interfaces but not on the bond0 interface

All the VLAN are working, we are able to ping other nodes in the different networks.

We created the Hyper-V external virtual switch named vSwitch bind on our bond0 interface.

New-VMSwitch -Name vSwitch -NetAdapterName bond0 -AllowManagementOS $false

The "Cloudbase Open vSwitch Extension" has been enabled on "vSwitch" Hyper-V virtual switch.

Enable-VMSwitchExtension -VMSwitchName vSwitch -Name "Cloudbase Open vSwitch Extension"

Within Open vSwitch we have br-int and br-tun bridges, for br-tun we can see all the VxLAN tunnels created and for br-int we can see the instance ports with the tags perfectly created.

We are able to spawn instances on this Hyper-V compute but the instances don't have network connectivity, the network interface is there but there is no DHCP address on it.

What step are we missing ?

Thanks for your help !

I can see the instance traffic in br-int and then in br-tun bridges but it's like if the traffic is not forward to vSwitch.

Hey. Thanks for trying this type of setup :). I wouldn't recommend mixing the MSFT multiplexor with OVS because we don't test that scenario very often. I would recommend using OVS bonds together with LACP...

To setup the vSwitch you are missing this part: https://github.com/cloudbase/ovs/blob/branch-2.7-cloudbase/Documentation/intro/install/windows.rst#add-multiple-nics-to-be-managed-by-ovs And for setting up OVS bonds I recommend looking over:

<p>https://blog.scottlowe.org/2012/10/19/link-aggregation-and-lacp-with-open-vswitch/ . I'll try to post tomorrow a small snippet as an example.

Also please let me know which version of OVS you are running. Please ensure that you have the latest Windows updates if you are planning to use the MSFT multiplexor solution.
