Yeah. Before issuing ssh command, I double check br0 is created by ovs-vsctl
and internal interface br0 is up by ifconfig.

Do you know whether br0 is actually up once the script terminates?
I've found that I sometimes need to explicitly 'ifconfig br0 up',
although I'm not really sure why.

Now I changed to your way, say from my own host, I issued
the following command:
ssh root@<remote host> "ovs-vsctl add-port br0
eth0; ifconfig eth0 0; ifconfig br0 <eth0's ip
address>"
However, I still lost connection to the remote host. Did
I still do sth wrong?
Best,
