The density range talks about the resources of the server, content of the server and the virtual environment in which all the things are taking place. The two most important resources that are required by any virtualization platforms are CPU and RAM. The more the processing power the fewer requirements will be for the offload processing. Virtuozzo achieves a high density for example of 100 virtual environments as it has minimal content and applications when used with Linux operating system but when used with windows more resources is being taken up by windows operating system.
