One of the benefits of adding VMM 2008 is that you can manage an ESX cluster from your MS network integrated management platform. In fact, you can manage many Virtual Center servers from a single VMM 2008 console/server. I’ve not tried it but based on the demo’s I’ve seen, you can do pretty much everything in the day-day side of managing VI3.
There’s a bug where this can happen. You add an ESX cluster to VMM 2008 but you are no longer able to add VM’s
Problem Description: Get this error:
VMM cannot find VirtualHardDisk object .
Ensure the library object is valid, and then try the operation again.
ID: 801
MS has published a hotfix for this … but it’s critical that you install this hotfix before adding ESX to VMM. If you didn’t and you get this bug then you should install the hotfix and run the script from the MS VMM blog.
