You can also build an MSI that you can deploy to targets for convenience.

To build the MSI you can issue:
`make windows_installer`

As a prerequisite you also need http://wixtoolset.org/releases/ installed
before issuing the command above.

I’ll try to send a PR to update the documentation.

Subiect: [ovs-discuss] 0VS on Win 10 - "failed to enumerate system datapaths"

Hi

Still struggling to get the ovs working on OVS windows 10.

Firstly I would like to ask the question, do I have to have hyper-v feature enabled even if I am not gonna run virtual machine but use ovs only within host machine.
[Alin Serdean] I’m not sure I follow, what are you trying to achieve?
You need to enable hyper-v/container feature wherever you want to use
the OVS windows datapath.

After compilation and install that what I get:-

C:\Users\...> ovs-dpctl show
2018-11-11T21:56:32Z|00001|dpif_netlink|INFO|The kernel module does not support meters.
2018-11-11T21:56:32Z|00002|netlink_socket|ERR|fcntl: The system cannot find the file specified.
2018-11-11T21:56:32Z|00003|dpif|WARN|failed to enumerate system datapaths: Invalid argument
[Alin Serdean] That means the extension is not installed or not enabled. Please follow the steps from:
http://docs.openvswitch.org/en/latest/intro/install/windows/#the-kernel-module


C:\Users\...> ovs-vsctl add-br br-int
ovs-vsctl: Error detected while setting up 'br-int'.  See ovs-vswitchd log for details.
ovs-vsctl: The default log directory is "C:/openvswitch/var/log/openvswitch".
[Alin Serdean] Same as above.

2018-11-11T22:02:58Z|00013|bridge|INFO|ovs-vswitchd (Open vSwitch) 2.10.90

I skipped the kernel module installation (run install uninstall.cmd) as I thought it relates to target machine only.

I also have Hyper-V feature not installed on my machine.

Any help would be appreciated
