Challenges of Virtual Machine Performance in Information and Computer Technology Virtual Lab Environments

This paper reviews common practices for minimizing virtual machine (VM) resource requirements. Also, the authors propose a novel nested VM architecture used in a cybersecurity virtual laboratory environment containing over 90 VMs on a single host. Using open source tools and minimizing the operating systems of VMs, the authors were able to significantly reduce VM resource requirements while increasing VM performance. This work provided helpful information for technology educators who seek to reduce their VM overhead and increase virtual lab environment performance. This paper also provided a groundwork for further research into maximizing virtual lab environment performance.
