The documentation states:
> If you clone a VM with journaling enabled, the clone snapshot will be valid. If not using journaling, first stop mongod, then clone the VM, and finally, restart mongod.

However, note that we have not supported turning of journaling for a long time, and since at least 6.1 the any remaining code and option is removed from the source code. This also seems to indicated that the entire VMWare section may need a check to make sure it still is up to date.
