Remove dangling plug-in from vCenter Server

by Philip Sellers

After completing our upgrade to vSphere’s version of vCenter Server, there were a few incompatible plugins left from our VI3 install.  Most of these were easy to remedy – especially the VMware provided add-on products like Converter and Update Manager which were on the same DVD media as vCenter Server.  But, if you have any third-party add-ins for vCenter, you may be left in a simliar situation to us.

We have tested many management products for ESX on our quest for the most appropriate product for our environment.  One of those products offered integration of their tool into vCenter by using a plugin.  Unfortunately, the plug-in didn’t have a nice uninstaller like the VMware provided plugins.  We were left with a nice red caution sign with an exclamation point.


After searching a bit, I came across this thread with a helpful solution – http://communities.vmware.com/message/1366557.  Thanks to user virtualchic for the solution…

  1. In a web browser, navigate to http://<<vCenter server name or IP>>/mob
  2. Click on “content”
  3. Click on “ExtensionManager”
  4. Select and copy the name of the plugin you want to remove from the list of values located under Properties.
  5. Click the UnregisterExtension option and a new window will appear.
  6. Paste in the name of the plug and click “Invoke Method” to remove the plugin.
  7. Close the pop-up window.
  8. Refresh the “Managed Object Type: ManagedObjectReference:ExtensionManager” window and the plugin should be removed from the list.

This successfully cleans up the list of plugins, however, I’m not sure if it completely cleans up the plugin or just removes it from view…
