# depmod -a
# /sbin/modprobe openvswitch
# /sbin/lsmod | grep openvswitch

export PATH=$PATH:/usr/local/share/openvswitch/scripts
# ovs-ctl start

# ovs-vsctl show
# ovs-vsctl add-br mybridge
# ovs-vsctl add-port mybridge eth0

# ovs-ctl stop Stop ovs service # ovs-dpctl show View the kernel, there will be a datapath of ovs-system
# ovs-dpctl del-dp ovs-system Delete the datapath that appeared in the previous step (if you do not do this step, rmmod may report an error)
# rmmod openvswitch Uninstall the openvswitch kernel module. Use lsmod | grep openvswitch to find no openvswitch.
