* Eventually, users should be able to reach *the state of virtual enlightenment* (tm), accepting the fact that their favorite operating system is running inside a virtual machine, and being able to take advantage of that new state of affairs.
> Phyllome OS has just started its journey and there is still a long, *years-long*, way to go to achieve its vision. It has several, [critical]() limitations.
[Support](/virt#guests) for guest systems differs widely. Have a look there
Phyllome OS exists in two main versions: **Phyllome OS Desktop**, which features a graphical desktop environment, and **Phyllome OS Server**, which does not. Phyllome OS Server is made for power users. It includes all virtualization enhancements that Phyllome OS Desktop provides, without the GNOME-based desktop environment.
If you don't know which one to choose, you should probably pick the Desktop version, which in turns comes in many flavors. There is a generic one, Phyllome OS Desktop, without out-of-the box support for nested virtualization. There are also other editions optimized for a particular combination of hardware.

Depending on your hardware, you need to pick the right edition. For example, if you possess an Intel CPU and an AMD graphics card, you should pick either Phyllome OS Desktop IA or Phyllome OS Server IA.
> As of now, **only Phyllome OS Desktop II is supported**. In other words, as of now, you need to use a computer with both an Intel CPU and an Intel GPU to leverage Phyllome OS. Support for other other editions are expected for the Beta.
> **Still undecided?** You can give Phyllome OS a try, as a live system booting off from a USB thumb drive, without impacting the existing operating system on your machine.
