◐ Close the app instead
A running VMware Fusion virtual machine.
What it is
Each running virtual machine reserves the memory you gave it.
If you close it
The virtual machine stops as if its power was cut. Shut it down from inside first.
The verdict
◐ Close the app instead. A part of an app. Closing it alone breaks something, so close its app.

From Procession’s guide, in the words the app shows.
