Qubes OS is a security-oriented operating system (OS). The main principle
of Qubes OS is security by compartmentalization (or isolation), in which
activities are compartmentalized (or isolated) in separate qubes.
Virtualization is performed by Xen, and user environments can be based on
Fedora, Debian, Whonix, and Microsoft Windows, among other operating systems.
This package contains the Qubes vchan communication libraries for Dom0 and VMs.
