I want to install mininet for my labs. I have been using garuda for a while and possibly don’t want to switch to ubuntu for just one application. Whenever I start mininet I get the following error.
sudo mn
[sudo] password for chhatra:
*** Creating network
*** Adding controller
*** Adding hosts:
h1 h2
*** Adding switches:
ovs-vsctl: unix:/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".
I tried the suggestions showing in the eror .
sudo ovs-vsctl show
[sudo] password for chhatra:
ovs-vsctl: unix:/run/openvswitch/db.sock: database connection failed (No such file or directory)
systemctl start openvswitch-switch
OUTPUT
Failed to start openvswitch-switch.service: Unit openvswitch-switch.service not found.
Is there a way to fix this error or run mininet on garuda
