Enkele dagen geleden is versie 3.0 van Qubes OS uitgebracht. Qubes OS is een op privacy en beveiliging georiënteerd besturingssysteem welk gebruik maakt van security by isolation, wat inhoudt dat de verschillende onderdelen van het OS in aparte vm's draaien. In tegenstelling tot bijvoorbeeld VMWare en Virtualbox is er geen host-os, maar draaien de vm's direct op de aanwezige hardware. De virtualisatie wordt door bare metal hypervisor Xen verzorgd en voor de gebruikersomgeving kan onder meer uit Fedora, Debian, Whonix en Windows worden gekozen. Meer informatie over Qubes OS kan op deze pagina worden gevonden. De belangrijkste verbeteringen in versie 3.0 zijn hieronder voor je op een rijtje gezet.
New features since 2.0Known issues
- HAL (Hypervisor Abstraction Layer) - based on libvirt, opens a whole new possibilities of using different hypervisors. Currently Qubes OS uses Xen.
- Xen 4.4 - many new features, but for us the most important is much more mature libxl toolstack.
- Qrexec 3 - greatly improved performance by using direct VM-VM connections and bigger buffers.
- Debian templates gets official support.
- Whonix templates
- Build system improvements - especially support for distribution-specific plugins (makes supporting multiple distributions much easier) and building templates using DispVM.
- Automated tests - makes much easier to find bugs, before its even shipped to users
- Windows Tools:
qvm-block
does not work- UEFI is not supported, you need to enable “legacy boot” in BIOS before installing Qubes OS
- Some icons in the Qubes Manager application might not be drawn correctly when using the Xfce4 environment in Dom0. If this bothers you, please use the KDE environment instead.
- If your GPU is not correctly supported by the Dom0 kernel (e.g. the 3D desktop effects do not run smoothly) then you might experience “heaviness” with Windows 7-based AppVMs. In that case, please solve the problem with your GPU support in Dom0 in the first place (by using a different kernel), or install Qubes OS on a different system.
