Dell Customer Communication
Thanks very much Qiming. It was the problem and I got it fixed by creating another port for the instance2.

B.T.W., another question. When I delete the stack, how come the network was not deleted? It seems only the instance was deleted. How do I clean up the networks and subnets associated with the instance using heat?

Thanks,

YuLing

It seems that you are sharing one port between two instances, which won't be a legal configuration.
