Quote from 0kelvinNot that many technical specs, but... What is that 3 OS running in the background, each one reserving 1GB for its own service? In PC you either have one OS or multiboot, there is no such thing as running two OS at the same time. For ex: in windows there are dozens of services, many of which can be deactivated. Now, what is that triple OS thing?
It's all virtualised. See here.
