I do still like the idea of having a client-side test that can just

This patch provides a relatively simple method for exercising various
features of qemu by interacting with the guest via serial and qemu
via the monitor that individual developers can use to validate that
their changes haven't broken feature/function. Such tests
need to be very accessable and
features against a set of images.
Patch 2/2 provides Makefile integration into qemu to execute qemu-test against
the current build of the tree. This can be done without the Makefile
integration, but simplifies the execution.
