Qubes OS 2 Beta 1 發布，基于Fedora的桌面Linux發行

Qubes OS是面向安全的、基于Fedora的桌面Linux發行，其主要理念是基于隔離的安全，而這靠輕量級的Xen虛擬機來實現隔離域。它旨在結合兩個貌似矛 盾的目標：如何使不同域之間的隔離盡可能強，這主要靠能夠使可信代碼盡量小的更靈巧的結構，以及如何使這種隔離盡可能無縫和容易。

Joanna Rutkowska has announced the availability of the first beta build of Qubes OS version 2, Fedora-based desktop Linux distribution whose main concept is
"security by isolation" by using domains implemented as lightweight Xen virtual machines: " It's my pleasure to announce that the first beta for Qubes Release 2 is now available for download. This release introduces generic support for fully virtualized AppVMs (called HVMs in Xen parlance), and specifically initial support for Windows-based AppVMs integration. Generic support for HVMs means you can now install many different OSes as Qubes VMs, such as various Linux distros, BSD systems, and, of course, Windows. Essentially all you need is an installation ISO and the whole process is similar to creating a VM in a program like Virtual Box or VMware Workstation (although we believe the underlying architecture for this is more secure in Qubes).
