The CentOS Cloud SIG (
https://wiki.CentOS.org/SpecialInterestGroup/Cloud ) is releasing a new OpenStack metadata package called CentOS-release-openstack-kilo that replaces CentOS-release-openstack. Metadata packages in CentOS
are used to setup the repositories used by the package manager ( yum )
and the signing keys used to validate content installed from the corresponding repositories. The present metadata package, called CentOS-release-openstack, does not allow for us to have multiple OpenStack versions available to users, without adding many layers of complexity to the install and update process.

This new OpenStack metadata package ( CentOS-release-openstack-kilo )
effectively sets up the mechanics required for us to deliver OpenStack Liberty as an alternative to users who might prefer the newer codebase, once it’s available. However, we would like to still support the users who have a Kilo install at the moment, and would like to run that as long as updates are available for Kilo itself.

Kilo to Liberty update process will require administrative actions, for details see “Upgrade Notes” in upstream release notes https://wiki.openstack.org/wiki/ReleaseNotes/Liberty

The metadata rpm for OpenStack Liberty will be called CentOS-release-openstack-liberty and users will be able to install it once released. For more information on our progress with that effort, please join the Cloud SIG meetings that are held weekly on
#CentOS-devel on irc.freenode.net or join us on the CentOS-devel mailing list ( https://lists.CentOS.org/ ).

The updated metadata package, CentOS-release-openstack-kilo, is now available on all CentOS mirrors, and can be installed by running either ‘yum update CentOS-release-openstack’ or ‘yum install CentOS-release-openstack-kilo’
