QEMU is about 600k LOC.  We have a mechanism to compile out portions of 
the code but a lot things are tied together in an intimate way.  In the 
long run, we're working on adding stronger interfaces such that we can 
split components out into libraries that are consumable by other 
applications.

Simplying forking the device model won't work.  Well more than half of 
our contributors are not coming from KVM developers/users.  If you just 
fork the device models, you start to lose a ton of fixes (look at Xen 
and VirtualBox).

So feel free to either 1) apply my previous patch and then start working 
on a "clean (and minimal)" QEMU or 2) wait to commit my previous patch 
and start sending patches to clean up QEMU.

Absolute none of this is going to give you a VirtualBox like GUI for QEMU.
