So is there any progress, or Xen will > not be in any near future release? Basically Xen did not mature in the fashion that I anticipated. As far as I can tell it is really only good for server consolidation for large Linux distro vendors. You need to have what amounts to a private branch. The xen developers don't appear to understand the importance of interface versioning. They broke ABI compatibility going from 3.0.2 -> 3.0.3 (trivial to fix, but that is not the point). When last I worked on it, they had one branch that was in constant flux and another branch that only received minor bug fixes and was 18 months behind from a functionality standpoint (think 5.x / 4.x). There are numerous other logging / supportability issues that I think are only addressed by the major distros. As it stood 6 months ago, unless you understood the internals of various bits of the code, there was no way of diagnosing failures due to a misconfiguration. This is not to say that it isn't cool technology, but rather that isn't going to be useful for the things I wanted to use it for so my time is being directed elsewhere. If I ever have a need for EC2 I may look at it again. One of the guys who ported FreeBSD to the xbox has expressed interest - so something may yet come of it. I'm happy to provide technical support to an individual who is largely self-sustaining in working on the code. -Kip
