Just a couple random suggestions:

- Drop SDL/VNC.  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.
