In the near future we'll publish a stable branch. There are actually 2
repositories: kernel repo, based on the latest kernel - 2.6.26 and a
userspace repository that will be based on kvm-68.

The idea is to maintain the above repos together and only apply bug
fixes. New features will come with every next kernel release.

We're in the process of creating an automatic test framework for kvm.
It will be open source framework based on autotest and similar to
Anthony's kvmtest. It will help stabilizing both the 'stable' branch and
the master.
