Windows Server 2008 does not run on the KVM version (36) in the CentOS repository. W2008 is the current version of Windows Server and not a Beta any more, so increasing numbers of people will be attempting to install CentOS+KVM+W2008, and running into difficulties.
KVM version 72 is required for W2008 according to this: http://www.linux-kvm.org/page/Guest_Support_Status
What needs to happen to get KVM-72 or later into a repository?
There is a very good KVM HowTo... http://wiki.centos.org/HowTos/KVM ...but it does not explain how to install a version that will run W2008.
I have documented a solution in this forum post... http://www.centos.org/modules/newbb/viewtopic.php?topic_id=19034&forum=3... ...but it relies on unofficial RPMs from www.lfarkas.org. Is it OK to put that advice in a HowTo?
It took me days of research, recompiling kernels and packages etc to get CentOS+KVM+W2008 working. I'm not complaining, it was fun, but I'm concerned that other people are just giving up and switching to Xen or Debian e.g. http://www.webhostingtalk.com/showthread.php?p=5606587#post5606587 ...and it would not take much to keep them on-board.
Thanks, Julian Price

talking to the people actually using kvm and centos on the centos-virt list would be a good place to start.
I should have said, I have posted on this subject to centos-virt. There were some useful suggestions for resolving issues with KVM configuration. Regarding what version of the RPM should reside in which repository, I was advised to post on this list.

ah! well, are you proposing to take ownership of this bit of code ? if so, propose a .spec file perhaps ?
Tim will prolly need to weigh in with views

It was more of a suggestion really.
I don't think I'm qualified to take ownership. I've used yum but I don't know how it works, same goes for KVM, and I'm not really set up for testing here either. I have been writing some KVM documentation for the Wiki though, and that's what led me to make this suggestion.

Since the packages in question
http://www.lfarkas.org/linux/packages/centos/5/x86_64/
are from Farkas Levente, who frequents this list, perhaps he would like consider offering them for inclusion in CentOS repos?

that would be quit cool. however, isnt there a problem with what runs on what ver of KVM ? in that centos-5 does not run beyond a certain release, whereas windows needs something else and opensolaris needs something completely different. or have those issues been resolved now ?
Does anyone know what @redhat.com folks are working on for EL5.4 / EL6 ? If possible, we could offer them access to our repo's so they could push testing builds and get a wider community feedback loop in place. </thinking out loud>

Farkas's version is KVM-84, which is the latest, and I have that running here on a clean install of CentOS 5.2 with one W2008 guest. Call it anecdotal evidence.
As for what will run on that version: http://lists.centos.org/pipermail/centos-virt/2009-February/000876.html "we only test with intel hosts and a dozens of guests, but this is the first series which seems to stable and really usable"
However, if that version goes into a repository and existing production installations do an update then they may get a KVM version that doesn't work for them. Or maybe it works but only after a config change. Is that the issue? Maybe it should go in the testing repository then.

Now run Centos 5.2 as another guest. Will that work as well? That seems to be the problem.

CentOS 5.2 on CentOS 5.2 works fine for me (with KVM 82/83 rpms from lfarkas.org on various x86_64 machines). I also have opensolaris, FreeBSD, and Windows XP guests on the same hosts.

If the KVM-84 binary RPMs already exist here...
http://www.lfarkas.org/linux/packages/centos/5/x86_64/etherboot-roms-kvm-5.4... http://www.lfarkas.org/linux/packages/centos/5/x86_64/kmod-kvm-84-1.x86_64.r... http://www.lfarkas.org/linux/packages/centos/5/x86_64/kvm-84-1.x86_64.rpm
...and have been in use for over a month, and nobody has found fault with them then does that mean that the tasks "Package, test, push to testers" are complete?
I think they should replace the KVM-36 RPMs in extras. However, if they are not ready then please can they at least be put into the testing repository so they can be tested more easily.
Regardless of what happens here, I think you should also raise the question on the Tikanga (RHEL5) list hosted by Red Hat.

Whatever CentOS (and Scientific Linux) folk do, if RH attends to it then their efforts are trumped.
KVM will become available from upstream, but not until RHEL 5.4... http://press.redhat.com/2009/02/23/open-source-innovation-strikes-again/
...when it looks like it will become the Next Big Thing. We can expect to see increasing interest in KVM leading up to that release from both CentOs and RH users, so making it available would make both groups grateful.

By all means point to your documentation, it will help generate interest.
