Hi! I've used two instructions from your side - http://www.cloudbase.it/open-vswitch-... and http://wiki.cloudbase.it/ovs-hyperv-a... but when I added bridge (or port) I received error like - Error detected while setting up 'external'. See ovs-vswitchd log for details First of all, there are no ovs-vswitchd log-file on the system. I can see ovs-vswitchd errors only if I start ovs-vswitchd in command line, or add '--log-file' option. As a result, ovs on hyperv doesn't work - in my case the instance can't receive IP-address and so on. I'm not sure where to attach logs, so here it is - From windows -

Hi IlyaSA, Sorry for the delayed response. But GRE is not currently suported by OVS 2.4.0. If you want to set up a Kilo environment you can follow the steps in the following link: http://www.cloudbase.it/open-vswitch-24-on-hyperv-part-1/.

Hi,

The reason you are getting the error is due to an outdated documentation.

Please refer to the following answer: http://ask.cloudbase.it/question/403/...

Short story instead of issuing:

ovs-vsctl.exe add-port br0 external

you should now issue:

ovs-vsctl.exe add-port br0 external.1

ovs-vsctl.exe add-port br0 internal

" In OVS for Hyper-V, we use 'external' as a special name to refer to the physical NICs connected to the Hyper-V switch. An index is added to this special name to refer to the particular physical NIC. Eg. 'external.1' refers to the first physical NIC on the Hyper-V switch.

Note: Currently, we assume that the Hyper-V switch on which OVS extension is enabled has a single physical NIC connected to it.

Interal port is the virtual adapter created on the Hyper-V switch using the 'AllowManagementOS' setting. In OVS for Hyper-V, we use a 'internal' as a special name to refer to that adapter."

Thank you it was helpful. And what about the command line 'ovs-vsctl.exe add-port br0 gre-1' I got the same error what do I have to type ? I have only 2 NICs in the compute node. The first one I called it 'external' which is the vswitch for hyper-v and it is considered as Data VM Traffic connected to the network node and the second one is considered as Management Network connected to the controller node

Hello and thank you for your answer. Also I need to thank you for the latest OVS from 01.09.15.Now I can add ovs-switch and there are no errors, Also, by your instructions,I can add 'external.1' and internal ports. But I have error when trying to add 'gre-1' port. Also, new release still has problem with creation of the ovs-vswitchd log - this file doesn't exist. Can you help me again?

At the current moment OVS 2.4.0 can only crash my system. I'll be waiting for the OVS's future releases with hope

OVS 2.5 has been released some time ago. You can try it out. https://cloudbase.it/openvswitch/
