The use of virtualization technologies to increase the capacity and utilization of laboratory resources is widely used in classroom environments using several workstation based virtualization products. These virtual networks are often \"air gapped\" to prevent the inadvertent release of malware. This implementation however requires users to be in the classroom. A novel extension on this concept is to design the infrastructure to support remote access to the virtual machine(s) using virtual server applications, while maintaining the complete isolation of the virtual networks.
