Hi

"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."
