Can you create a VM without snapshot capability?
If you do not take a snapshot, your virtual machine runs the same way a physical computer does. All changes you make while you are working with a virtual machine are saved and you cannot return to an earlier state. If you do not need to use the snapshot feature, it is best to run your virtual machine with no snapshot.

Why VMware snapshots are bad?
In the event that the VMFS volume does fill, the current snapshot file won’t be able to accept writes, and the virtual machine will promptly crash. All of them require the use of VMware’s VMware Tools package that is commonly installed within the virtual machine’s operating system.
