Regarding " User can specify the IP address from the guest subnet if not CS picks the IP from the guest subnet " comment in the FS
I don't see a need to do this - because, it is a shared network, how does he know what is used up and what is not? So, he could go through a sequence of steps only to get an error message back that it is not possible (and keep doing this until success) One possibility is telling him what is available - it may not be a big deal to reveal the used/unused IPs in isolated network (although it would be hard to show from a large CIDR what is used/available), but we wont even be able to tell him what is used/unused in a shared network - Any thoughts?

At some point, we're going to be asked, so I'd like to have a decent answer. :) On the rest of this, I'd like to get some level of consensus on the design. What looks best to me: * Improve UserData/CloudInit support in CloudStack (I'm willing to work on this, consider it important) - allow expiration of data, wider variety of data supported * Create the multi-IPs-per-NIC code to get IPs via CloudInit (Need to think through Windows equivalent) * Update the password changing script to use CloudInit Thoughts? Or Jayapal have you already started work on the multi-IP feature?
