vAPP IP address pools in vCenter - The feature that wasn't

The IP Pools feature of vCenter is not really fully implemented, at least not in a way that an end user can easily work with them. Documentation is non-existent, other than blog articles and books. Mike Laverick gives us some insight in his book, VMware vSphere™ 4 Implementation (reference below)

Mike Laverick's book (ch. 11) explains that even once you set up the IP pools, configure the vApp to use them, configure the VM to obtain them, it's still up to the end user to implement them. The IP pool info is delivered to the VM via ISO or VMware Tools (as an environment variable). It's up to the end user to create a script that actually changes the IP address.

Thanks to VMware for almost giving us what we needed...

  1. For anyone who's used lab manager, this was indeed a huge let down. When I initially saw the tab I assumed I could just add some space and vcenter would do the rest. After a week of frustration with the severe lack of documentation and a support ticket with vmware, I finally gave up still not fully understanding how to implement it even with vapps. It's almost like the lab manager style ip allocation was what they started to implement but they just stopped played xbox instead.

  2. You may be right, Brian, about Lab Manager being the inspiration for this attempt at a feature. It occurs to me that since Lab Manager was being distorted into VMware Cloud Director, they just gave up putting the feature into vCenter. Too bad, since not everyone wants the Enterprise License you need to make vCenter work well.
    Thanks for posting, you're the first! (besides me!).
