Apart from that I'm not aware of any major regression (wearing arm-linux-user, some arm-softmmu and debian hats).I'd say the two qcow2 data corruption bugs are a major regression. (Both reported in in another thread). qemu 0.9.1 has the qcow2 code from kvm-72, which doesn't exhibit either of those corruption bugs. A new release based on current kvm userspace would introduce those bugs. One of the bugs (reported by Marc) corrupts a qcow2 image so you can't use it even if you revert to an older qemu/kvm. It's not clear if the other bug causes permanent corruption itself, but anything which causes a guest to see the wrong data can lead to the guest writing corrupt data elsewhere later on. Simply reverting the qcow2 code appears to fix those problems, so it needn't hold up cutting a release. That's what I recommend.
Send some patches. Regards, Anthony Liguori
