%description
Looking Glass is an open source application that allows the use of a KVM
(Kernel-based Virtual Machine) configured for VGA PCI Pass-through without an
attached physical monitor, keyboard or mouse. This is the final step required
to move away from dual booting with other operating systems for legacy
programs that require high performance graphics.
