Release notes


What is VirtIO/BLK?

VirtIO and VirtBLK is in short, the closest you get to doing full virtualization. Usually an operating system is running ON the virtualisation platform, this was the case with all our preious Windows based operating systems. These operating systems didn’t know wether they were running on physical hardware or on a virtualized platform and the communication between the actual computing power (CPU, RAM) and the software is emulated in the virtualisation platform to resemble a physical environment.

With VirtIO/VirtBLK you could say that the OS is aware of the fact that it´s running on a virtual environment and co-operates with the hypervisor. The hypervisor is the same as a management system (KVM) that keeps track and allocates resources for all the virtual instances. This way, the OS becomes more integrated with the platform and you no longer need to emulate the communication between the platform and the OS. Naturally, this increases communication speed and in turn performance.


Debian 7

Multiarch support, one of the main release goals for “Wheezy”, will allow Debian users to install packages from multiple architectures on the same machine. This means that you can now, for the first time, install both 32- and 64-bit software on the same machine and have all the relevant dependencies correctly resolved, automatically. /From Debian.org
