Make a proper Cairo GUI with a full blown GTK interface. Don't rely on virt-manager for this. Not that I have anything against virt-manager but there are many layers between you and the end GUI if you go that route. - Sandbox the device model from day #1. The size of the Linux kernel interface is pretty huge and as a hypervisor, it's the biggest place for improvement from a security perspective. We're going to do sandboxing in QEMU, but it's going to be difficult. It would be much easier for you given where you're at.
