Hi Wido, At the moment, we're running Ubuntu 14.04 LTS using the Ubuntu Cloud Archive. To be precise again, it's QEMU/KVM 2.3+dfsg-5ubuntu9.4~cloud2 linked to Ceph 0.94.8-0ubuntu0.15.10.1~cloud0. So yes, it's all about running a newer QEMU/KVM on a not so new version of Ubuntu. Question is, are we able to run against a Ceph cluster running Jewel instead of Hammer. Or, do we need to upgrade our OpenStack installation first? Regards, Kees On 13-12-16 09:26, Wido den Hollander wrote: > Why?
