kilo testing EL7 was moved to production last night,
Fedora is in progress (incomplete repo)

UPDATE 05/08/2015
Devstack install Openstack Kilo tested on Fedora 21 (VM,Nested KVM enabled, 8 GB RAM, 4 VCPUS) with required rawhide upgrades OK.
END UPDATE

At the moment RDO KIlo ( yum install http://rdoproject.org/repos/openstack... ) worked for me only on CentOS 7.1.
However, there is chance to setup Kilo via Devstack on F21 . View for instance :-

You may track details regarding RDO Kilo on Fedoras 21,22 via https://trello.com/b/HhXlqdiu/rdo
On Fedora 21 (yum updated) attempt :-

 # yum -y install git  python-six  fedora-repos-rawhide
 # yum --enablerepo=rawhide install  python-pip python-pbr systemd
 $ git clone https://git.openstack.org/openstack-dev/devstack
 $ cd devstack
 $ git checkout -b kilo origin/stable/kilo

$ cat local.conf

Run ./stack.sh and see what happens

I've tried packstack + F21/CentOS 7.1/RHEL 7.1 + Kilo and it works
