Linux "The team led by security expert Joanna Rutkowska has released the first beta version of the Qubes OS Linux distribution. The operating system can also be installed on a USB stick thanks to its new installer. Qubes aims to provide security through virtualisation. It uses a Xen hypervisor to run applications in separate virtual machines based on Fedora 14. As a result, online banking data are not at risk when a game running in its own VM turns out to be a trojan."

RE[2]: Solaris does this

Member since:

I was also wondering why they went with Xen and not OpenVZ. OpenVZ provides containers like Zones in Solaris. Like you mention, using containers could've probably been a lot lighter on the resources.

To answer your question, let us go to the website in question , why they designed that thing on top of Linux:

Qubes is an open source operating system designed to provide strong security for desktop computing. Qubes is based on Xen, X Window System, and Linux, and can run most Linux applications and utilize most of the Linux drivers. In the future it might also run Windows apps.

The keywords are "most Linux applications and utilize most of the Linux drivers" and "desktop computing." Whatever the Solaris or BSD world can offer with million light years ahead of being cooler than any Linux solutions _without_ APPLICATIONS and DRIVERS support, Solaris and BSD are nothing but a bunch of two different words. They are "cool" given if you use them properly, but if you want to run diverse applications with it and peripheral support, then it is useless.
