Where will the Xen.org community take Xen 4.0?

The Xen community is releasing updates to the hypervisor technology in quick order. What do they have on tap for the Xen 4.0 road map?

The Xen community launched Xen 3.4 back in May of this year.  The release added quite a few new features, chief among them being support for the Microsoft Hyper-V enlightenment interface, power management, CPU and memory offlining, and device pass-through improvements.  A short time later, the community released Version 3.4.1, a maintenance release.

We can expect to see a series of quick dot releases like this in the future.  Community leaders said that rather than focus on the "big bang" 12-month development cycle, as they did with Xen 1.0, 2.0, and 3.0, the group plans on releasing updates in a far more incremental process.  The group's goal is to go through a stabilization phase first, and then come out with point releases every 10-12 weeks.  Much like with Linux, these point releases will be maintained with bug fixes until the next point release.
