check if vswitchd is running (ps aux|grep vswitchd) and check it logs for errors.

Dear All,

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,
Talal
