When I enable DRS on any of my clusters, I can no longer Vmotion VMs or power on inactive VMs. If I disable DRS I can do both of those tasks. The error I receive says something about objects not existing, or have never existed (see attachment). Problem started occurring following the VC upgrade to 2.5.
Help?
I would take a look at the License Server and make sure that is working correctly. You could also try creating another cluster that has HA and DRS enabled and add the ESX hosts to see if that helps resolve the issue.

The clusters are brand new because HA didn't work after the upgrade either and I had to do exactly what you suggested. But thanks for the suggestion.
I had similar problems and had to follow the last post in the thread below. I tried removing, adding back, moving in/out of the cluster, etc. before verifying that version.
One solution I've tried so far that worked was to disable DRS and enable it again, but in a existing environment it can be annoying.
