This allows the segmentation of applications into secure <a href="/wiki/Virtual_machine" title="Virtual machine">virtual machines</a> called qubes. Virtualization services in Qubes OS are provided by the <a href="/wiki/Xen" title="Xen">Xen</a> hypervisor. </p><p>The runtimes of individual qubes are generally based on a unique system of underlying operating system <i>templates</i>. Templates provide a single, immutable root file system which can be shared by multiple qubes. This approach has two major benefits. First, updates to a given template are automatically "inherited" by all qubes based on it. Second, shared templates can dramatically reduce storage requirements compared to separate VMs with a full operating install per secure domain. </p><p>The base installation of Qubes OS provides a number of officially supported templates based on the <a href="/wiki/Fedora_(operating_system)" class="mw-redirect" title="Fedora (operating system)">Fedora</a> and <a href="/wiki/Debian" title="Debian">Debian</a> Linux distributions.

I had been treating Qubes as a security enhanced Linux distribution, as though it were a regular desktop operating system with some added security. This quickly frustrated me as it was difficult to share files between domains, take screen shots or even access the Internet from programs I had opened in Domain Zero. My experience was greatly improved when I started thinking of Qubes as being multiple, separate computers which all just happened to share a display screen. Once I began to look at each domain as its own island, cut off from all the others, Qubes made a lot more sense. Qubes brings domains together on one desktop in much the same way virtualization lets us run multiple operating systems on the same server.</p></blockquote> <p>Kyle Rankin from <a
