[libvirt-users] qemu-kvm version for CentOS
WHY CentOS still using qemu-kvm 0.12? What I am need is high version of qemu-kvm for CentOS, but seems like they do not officially provide newest qemu, only qemu 0.12 source code with 3522 patched rpm package. Is there any reasonable to keep low version for qemu-kvm ? or what should I do if I need newest qemu-kvm rpm package? ✉ -- 朴元奎 kerwin
Centos is not going to generally have the cutting edge stuff. For that why not try fedora which will generally package with the newest libraries from various packages, including qemu . I think the current fedora repos have qemu 2.1

qemu 2.1 is not released yet, but yes, rawhide (and therefore the fedora-virt-preview repo on Fedora 20) are currently shipping qemu 2.1-rc0 (and soon rc1). Note that 2.1-rc0 has a bug that prevents libvirt from using qemu properly, which upstream qemu hopes to have fixed in time for the actual 2.1 release.

Because CentOS borrows from RHEL, and the engineers at Red Hat have determined that enterprise stability is worth backporting thousands of carefully vetted patches rather than rebasing potentially unstable code that picks up even more unaudited upstream commits. If you need newer code but still with assurances of enterprise quality performed by Red Hat, then consider using RHEL 7.0 (and CentOS 7 can't be too far behind...) -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

With distros it's always a question of stability vs bleeding edge. It's not possible to have git builds every day and guarantee enterprise stability at the same time. CentOS and RHEL are distributions that prefer enterprise stability to the latest versions of all packages. If you, however, want newer version of some package, you can still download its source code and build it from there. Or use a distribution that packages only the fresh new stuff out there. Michal

The CentOS virt sig would be one to follow here. http://wiki.centos.org/SpecialInterestGroup/Virtualization
