After an unusually long release cycle, kvm-85 has been released featuring the new split tarballs for userspace and kernel components. The separate components can be mixed and matched and gives you the option of using the kvm kernel module that comes with your Linux distribution. The upcoming stable branch will be based on these separate packages. As expected, this release includes another merge with qemu featuring some interesting changes such as multiple simultaneous vnc client support and VNC access lists.
