When you add a compute manager, NSX Manager adds its identity as an extension in vCenter Server. If you do not want to register this vCenter Server to any NSX-T Data Center installation, you can remove the extension through the vCenter Server's Managed Object Browser (MOB).


  1. Log in to vSphere web client as an administrator.
  2. Select the ESXi host.
  3. Click the Manage > Settings tab.
  4. Select Advanced System Settings from the menu.
  5. Enable the Config.HostAgent.plugins.solo.enableMob option.
  6. Login to the MOB.
  7. Click the content link, which is the value for the content property in the Properties table.
  8. Click the ExtensionManager link, which is the value for extensionManager property in the Properties table.
  9. Click the UnregisterExtension link in the Methods table.
  10. Enter com.vmware.nsx.management.nsxt in the value text field.
  11. Click the Invoke Method link on the right hand side of the page below the Parameters table.
    The method result says void but the extension will be removed.
  12. To make sure the extension is removed, click the FindExtension method in the previous page and invoke it by entering the same value for the extension.
    The result should be void.
