I don't fully understand the concept of virtual labs yet. It seems to me that the virtual labs are always connected to the production network. But in that case I must not start any production vm in the virtual lab, because it would collide with the existing vm in the production environment or am I wrong?
I would like to have a virtual lab, which is completely isolated. I would like to start some VMs in that environment, e.g. DC, DNS, DHCP and I would like to test modifications in that environment (e.g. Microsoft Hotfixes) to make sure that they work. Is that possible?
