Open Stack

Kumar,

I haven't worked very much with the CloudFormation resource types, which is what that template uses. Thus, I am unsure of the exact syntax you should use in order to correct the problem you're seeing.

However, take a look here:

<https://ask.openstack.org/en/question/10085/multiple-possible-networks-found-use-a-network-id-to-be-more-specific/>

Based on that information, it looks like you just need to add a SubnetID to the WebServer, and the value of the SubnetID will be the UUID of the appropriate Neutron subnet. I'm not sure how to add multiple subnets to a single instance; I would suggest making the template work with one network interface first, then move to multiple network interfaces.
