Having reached a good break point in my Gluster/Openstack/Fedora tests, I thought I’d preupgrade the F16 VM I’ve been using for ovirt engine to F17, en route to the oVirt 3.1 beta.
That didn’t go so well. During the post-preupgrade part (uh, the upgrade), the installer balked at upgrading the jboss-as package that shipped with oVirt 3.0. Afterward, the VM wouldn’t boot correctly.
Fortunately, I was prepared for failure, detaching my iso domain in advance, and shuttling the templates and VMs I wanted to keep to the export domain, which I also detached.
