[ovs-discuss] Question about Remote Control of OVS-daemon

[陈文龙]

Firstly, run ovs daemon on host3.
Then, host1 and host2 run ovs connect to host3.
What you do on host3 would be done on host1 and host2.

For example,
IP of host1, host2, host3 is ip1, ip2, ip3.
ovs listen on port

On host3:
ovsdb-server /path/to/db --remote=tcp:port
ovs-vsctl --db=tcp:ip3:port init
ovs-vswitchd tcp:ip3:port

On host2, host3:
ovs-vsctl --db=tcp:ip3:port init
ovs-vswitchd tcp:ip3:port

>From now on, do everything on host3.
e.g.
host3# ovs-vsctl --db=tcp:ip3:port add-br br0
That would create bridge br0 on each host.
