Hello,

we currently test hyperv and openstack with Kilo. The launch of the Windows Instance works perfect, but the virtual NIC of the VM is not connected to the virtual external Switch: 2016-08-02T14:11:40.763Z|00023|wmi|WARN|Could not get the first MsvmVirtualEthernetSwitchSettingData object 2016-08-02T14:11:40.764Z|00024|wmi|WARN|Could not find HRESULT description for: 0. 2016-08-02T14:11:40.764Z|00025|dpifnetlink|ERR|Could not create wmi internal port with name:br0 2016-08-02T14:11:40.764Z|00026|dpif|WARN|system@ovs-system: failed to add br0 as port: Invalid argument 2016-08-02T14:11:53.463Z|00027|wmi|WARN|Could not get the first MsvmVirtualEthernetSwitchSettingData object 2016-08-02T14:11:53.464Z|00028|wmi|WARN|Could not find HRESULT description for: 0. 2016-08-02T14:11:53.465Z|00029|dpifnetlink|ERR|Could not create wmi internal port with name:br0 2016-08-02T14:11:53.465Z|00030|dpif|WARN|system@ovs-system: failed to add br0 as port: Invalid argument 2016-08-02T14:11:53.465Z|00031|dpif|WARN|system@ovs-system: failed to add external.1 as port: Invalid argument 2016-08-02T14:15:41.073Z|00032|dpif|WARN|system@ovs-system: failed to query port : Invalid argument

Here is my output from the ovs: PS C:\Program Files\Cloudbase Solutions\Open vSwitch\bin> .\ovs-vsctl.exe show 3e7f9559-80d2-446c-8eeb-138929290bd9 Bridge "br0" Port "external.1" Interface "external.1" Port "br0" Interface "br0" type: internal

We using currently VXLAN, so do i have to create a new Interface on OVS for VXLAN (type=vxlan)?

Thanks for your help.

Hi,

Thanks for trying out OVS on Windows :)

From the port usage ("external.1") I am guessing you are using the 2.4 guide, which is now deprecated, please refer to the updated guide: OVS 2.5

Could you please post on http://pastebin.com/ the output of the following commands: Get-NetAdapter, ipconfig, systeminfo, Get-VMSwitch *, Get-VMSwitchExtension *, ovs-vsctl show, ovs-dpctl show

Thanks,

Alin.
