[ovirt-users] How can I let others safely manage there own virtual machine

Hello, I'm new to this so I was wondering if anyone could give me some tips. I work for a company and we deploy software which needs to work together with other software, domain policies, proxy, etc. For this we often set up a new virtual machine to simulate potential problems and give us the opportunity to investigate. So I was wondering how do I best go about doing this and give multiple users the ability to create new machines from templates but put restrictions on how many vm's they can create, the disk space they use and the network bandwidth they use. If there is a way to also limit in time how long the created vm's can exist would also be very interesting. Kind regards.
