[Openstack] [OpenStack] VM start up with no route rules

Thanks for your analysis. Finally, I found there are two DHCP ports when I create a tenant network with DHCP enabled. That makes VM cannot start up due to fail to get its ip address. 

But why there two DHCP ports when I create the network is still under investigation. Do you have some hints for this? Thanks.

Does your VM's interface also have DHCP enabled? If it's configured to  
have a static address, it won't be changed by dhcp. Have you used the  
image outside of heat and did it work with dhcp for a single VM?
