Warning: Deleting a virtual machine deletes all data saved on that machine. If data on a virtual machine needs to be saved, back up your data before proceeding with the instructions in this article.
To delete a virtual machine:
In Fusion, go to Window > Virtual Machine Library.
Power off or suspend your virtual machine.
Right-click the virtual machine and select Delete.
When prompted, select Move to Trash.
Note: Selecting Keep Files, rather than Move to Trash, removes the virtual machine from your Virtual Machine Library, but leaves the files that make up your virtual machine intact on your Mac. These files can be opened later or moved to another computer.
For more information, see:
Uninstall a Virtual Machine by Using the Virtual Machine Library section in the VMware Fusion Help guide.
