When you create the ADVL project you have the option to select the host, folder and storage for each VM that is created. You can also configure the processors, RAM, Disk Volumes and the number of NICs as well as the TCP/IP Settings for each NIC.
When you run the project, the source computers selected in the project are created as VMs per the options you select, with all of the NICs disabled. Once the virtual test environment has been completed, the ADVL console will display a prompt asking if you want to enabled the NICs or cancel. You need to ensure the VMs are isolated before you enable the NICs to ensure there is no conflict with the production domain. Clicking Cancel will leave the NICs disabled and you can then enable them later once you have ensured the VMs are isolated. Once the VMs are created, you can move them or do anything else with them that you would with a regular VM.
