Enhancing libvirt with SELinux support

The libvirt project offers a virtualization abstraction layer, through which administrators can manage virtual machines without direct knowledge of or expertise in the underlying virtualization platform. As such, administrators can use the libvirt-offered tools to manage virtual machines running on QEMU, QEMU/KVM, Xen, and so on.

To use the sVirt approach, libvirt can be built with SELinux support. When this is the case and the guests are governed (security-wise) through SELinux, then the sVirt domains and types are used/enforced by libvirt. The libvirt code will also perform the category selection to enforce guest isolation and will ensure that the image files are assigned the right label (image files that are in use should get a different label than inactive images files).
