Hi Gianluca, it took me some time to correct my misunderstanding. I advised to update only libvirt as I was aware of the (old) block-commit command of qemu. With that you can merge snapshots in the chain (history) but not into the active layer (the current running state). Merging data into the active layer needs active-commit that is available since qemu 2.0 . That explains the error you got.
OVirt makes use of the second scenario so no luck without a full installation of virt-preview repos or a jump towards FC21.

I will have a look what qemu 1.6.2 might need. Regarding stability of qemu 2.1.2: You should scan the qemu stable mailing list if some severe fixes have been posted after the release. If you feel comfortable take qemu from the preview repos too. Just a simple yum update. Remark: With the advent of FC21 virt-preview for FC20 might see no further fixes.

I didn't notice that only the libvirt part is included in the ovirt-3.5-fedora-virt-preview repo: " [ovirt-3.5-fedora-virt-preview] name=Virtualization packages from Rawhide built for latest Fedora baseurl=http://fedorapeople.org/groups/virt/virt-preview/fedora-$releasever/$basearch enabled=1 skip_if_unavailable=1 gpgcheck=0 includepkgs=libvirt* " SO I think I need qemu-2.1.2-6.fc20.x86_64.rpm and probably other packages as provided by virt-preview. What could be the safest way to include further qemu packages? How stable is qemu 2.1.2 at this time? Thanks, Gianluca
