QemuX – written by René Korthaus – claims to be a powerful UI (User Interface) for the Qemu CPU Emulator by Fabrice Bellard. QemuX is designed for Mac OS X. As qemu currently only runs as a Terminal App, a Cocoa application for managing configurations and simple launching of a Guest OS makes your life easier. [1] I also advise to follow qemu-devel [2].
