VMware: VMDebug driver (version was not enabled


Yesterday I was upgrading my Citrix farm running on ESXi 4.1, after upgrading the VM with some updates the server crashed, received warning:

VMDebug driver (version was not enabled.  This driver is required by the replay debugging feature of VMware Workstation. If you are using other VMware products or not using replay debugging, please ignore this message.






The virtual machine debug driver is not required in an ESX host. The driver is used for record/play functions in Fusion and Workstation products.

To prevent the message from appearing, browse to:


Change the Start key from 1 to4. This disables it.
