" Dear Dennis,

We use VMWare Workstation 14 at work as the hypervisor for a number of virtual machines that run on our server. A few days ago we lost power on the server while our database virtual machine (VM) was running. I have since tried to start that virtual machine, but VMWare Workstation keeps popping up with an error message that says 'This virtual machine might have been moved or copied (pic). In order to configure certain management and networking features, VMWare Workstation needs to know if this virtual machine was moved or copied. If you don't know, answer 'I copied it'. I then have the choice: 'I moved it', 'I copied it' and 'Cancel'. I have tried 'I moved it' and 'I copied it' and VMWare Workstation tells me that 'Taking ownership of this virtual machine failed' (pic). I cannot start the virtual machine. We really need to get to our databases - can you please help? "

My response:

I asked if Paul would like me to connect to his server using my remote desktop support service in order to have a closer look, and he agreed.

Below I will discuss my findings.

How to Fix: VMWare 'Taking ownership of this virtual machine failed' Error

The error message "Taking ownership of this virtual machine failed" (pic) may occur when you move or copy a virtual machine, in the event if power is lost on the host, or if the virtual machine is corrupt. To avoid losing power to a virtual machine, the host / server / machine running the hypervisor should have an uninterrupted power supply (UPS) and a RAID with battery backup.

That said, there is a way to fix this problem, which requires manually moving around some files where the virtual machine is stored.

To do so:

  1. Pause or power off any running virtual machines inside the VMWare Workstation hypervisor.
     
  2. Next, launch Task Manager by pressing CTRL + ALT + DEL on the keyboard. Go to the "Details" tab (for Windows 8 and 10) or the "Processes" tab in Windows 7 and earlier. Next, sort the processes by clicking on the "Details" or "Processes" tab and look for "vmware-tray.exe" in the list of running tasks. Highlight the "vmware-tray.exe" task by left-clicking the mouse, then press DEL on the keyboard to end it.
     
  3. Go to the folder containing the problematic virtual machine. Next, look for any ".lck" or ".lock" files AND folders. Select each one by holding down the CTRL key on the keyboard while you left click the desired files / folders. Once all items have been selected, right click over one of them and select "Cut" from the dialogue menu.
     
  4. Next, create a "Temp" folder inside the directory, then right click over top of Temp and select "Paste". The items you highlighted in Step #3 should be moved to the Temp folder.
     
  5. Start VMWare Workstation again. Click Start, then type in "VMWare Workstation"; wait for "VMWare Workstation Pro" or such to appear in the list, then click it. This will start the VMWare Workstation hypervisor. If it does not launch full screen, go to the task bar (by the clock) and locate the VMWare Workstation icon, then double click it to open it full screen. Locate your problematic virtual machine, then start it.

At this point, the virtual machine should now start. If it does not then you are welcome to contact me for additional support, described next.
