Restricting users to only interacting with their own created VMs?

[Victor Hooi]

Hi,

We have a test environment setup with various shared templates (e.g.
Windows 7, Windows 8.1, Windows 10) etc.

We have a number of users who login, clone those templates, and do their
own testing on their own VMs.

What's the easiest way to restrict users to only interacting with VMs
created by themselves?

Thanks!
