Fail to Run Openvswitch 2.5.0

I've removed the openvswitch version I had, and I downlaoded version (2.5.0) following the same steps in this link (https://github.com/mininet/mininet/wiki/Installing-new-version-of-Open-vSwitch) and instead of (OpenVSwitch 1.10) I used (OpenVSwitch 2.5.0). The installation went smoothly without error, but when I try to run mininent and got the following error. I've tried some suggestions I found online but none of them works.

ovs-vsctl: unix:/usr/local/var/run/openvswitch/db.sock: database connection failed (No such file or directory) ovs-vsctl exited with code 1 *** Error connecting to ovs-db with ovs-vsctl Make sure that Open vSwitch is installed, that ovsdb-server is running, and that "ovs-vsctl show" works correctly. You may wish to try "service openvswitch-switch start".

Could you please advise me what to do ?

Cheers, Tom

We need 2 processes for that.

  • ovsdb-server
  • ovs-vswitchd

These 2 will be started with following command.

/usr/local/share/openvswitch/scripts/ovs-ctl start

In my case, /usr/local/share/openvswitch/scripts is the default location for ovs-ctl scriot, Hope that helps.
