Qubes OS

Qubes OS

Qubes OS è una distribuzione Linux per desktop basata su Fedora e orientata alla sicurezza. La distribuzione utilizza una leggera  macchina virtuale Xen per attuare un isolamento tramite domini.

Versione 3.0

Questa versione contiene (in Inglese):

  • Qubes is now based on what we call Hypervisor Abstraction Layer (HAL), which decouples Qubes logic from the underlying hypervisor. This will allow us to easily switch the underlying hypervisors in the near future, perhaps even during the installation time, depending on the user needs (think tradeoffs between hardware compatibility and performance vs. security properties desired, such as e.g. reduction of covert channels between VMs, which might be of importance to some users). More philosophically-wise, this is a nice manifestation of how Qubes OS is really “not yet another virtualization system”, but rather: a user of a virtualization system (such as Xen).
  • We upgraded from Xen 4.1 to Xen 4.4 (now that was really easy thanks to HAL), which allowed for: 1) better hardware compatibility (e.g. UEFI coming soon in 3.1), 2) better performance (e.g. via Xen’s libvchan that replaced our vchan). Also, new Qubes qrexec framework that has optimized performance for inter-VM services.
  • We introduced officially supported Debian templates.
  • And finally: we integrated Whonix templates, which optimize Tor workflows for Qubes.
