I've been chipping away at what it would take to upgrade our Fedora CI jobs to Fedora 21. The motivation was primarily that Fedora 21 has more recent packages which would simplify some of the package requirements in Delorean. Besides this Fedora 21 has been out for months now so we really should be using it already... Here is what I've found so far: https://review.openstack.org/#/c/161836/ (Create Fedora 21 softlink for /var/run/mariadb) https://review.openstack.org/#/c/161840/ (Work around 20-neutron-selinux issues on F21) Can someone have a look at a proper fix here? https://review.openstack.org/#/c/162442/ (Fedora 21 tftp files fix... copy in syslinux modules) Install Fedora kernel-modules pkg for iscsi_tcp (https://review.openstack.org/#/c/162443/) For TripleO CI: https://review.openstack.org/#/c/162399/ (Add support for Fedora 21 image downloads) Lastly there is this CI job where I've been initially testing things: https://review.openstack.org/#/c/161277/7 The Job is almost working (after cherrypicking all the above fixes) except for the fact that there is an open qemu-img bug that is exposed by our Cinder Glance image conversion code. See here for details https://bugzilla.redhat.com/show_bug.cgi?id=1200043. We can either fix this bug... or patch Cinder to avoid it (perhaps by using -t writeback... thanks eharney for help with this!). Dan
