Cannot Delete a Virtual Machine(Another task is already in progress)

KB ID 0000376 Dtd 17/01/11

Problem

When you try and delete a Virtual Machine from ESX or VSphere you see the following error.

Error: Another task is already in progress.

Another task is already in progress.

Another task is already in progress.

In addition, if you try and remove the VM from the inventory you will see the following error.

Error: Call “VirtualMachine.Unregister” for object “{vm name}” on vCenter Server “{VCenter name}” failed.

Error: Call "VirtualMachine.Unregister"

 

Solution

In my case the VM in question was in the middle of a hardware upgrade (from version 4 to Version 7) that had failed/stalled.

Select the VM in question then open its summary tab. Simply cancel the the stalled upgrade and click OK.

vm hardware upgrade

You can now remove the VM as normal.

delete vm
