So I went there hoping to find a version maintainance policy like that of the linux kernel, that is, the last number in the release version is the patch level. Usually in linux I go hunting for the last kernel version which ends with a .3 or higher, for production use, e.g. as of today I wouldn't choose 2.6.37(.0) beacause .0 is not enough stable for a production server imho, I would choose 2.6.36.3 I was trying to do the same with KVM but when I saw the changelogs I realized that the stable kvm releases are not really stable in this sense. E.g. in the 0.12.4 there are a helluva lot of changes which are feature improvements (hence adding potential bugs), or so seems to me: http://garr.dl.sourceforge.net/project/kvm/qemu-kvm/0.12.4/changelog Am I correct? So there is no "maintenance line" in KVM where, after a release with new features, you only add bugfixes for later point-versions? So our likelihood of getting regression bugs is basically the same for every qemu-kvm version; so we should just choose the latest qemu-kvm, i.e. right now we should choose 0.13.0 instead of 0.12.5 ?
