UnetLab Installation Since UNL is a separate project with its own evolving documentation I won’t try to reproduce it in my blog and I’ll simply refer all my readers to UNL download page, UNL installation instructions and UNL first boot configuration. At the time of writing UNL is distributed as an image packaged in Open Virtualization Format. I’m using VMWare Workstation as a type-2 hypervisor to import and run this image.
