fedora 32 is no longer reciving any security or package updates as its EOL
if you do base you deployment on fedora core os i would suggest using a more recent version.
im not sure if will work with magnuma but i dont think we really should recommend using an unsupported
OS for any new deployments.
keep im mind that fedroa support policy is 2 release +1 month for hte base os.
that tipically means its only supported for 13 months
fedora 32 becamue EOL on 2021-05-25 3 months ago
ideally if you are using fedora core os you would start form the most recent release and subscipe to t the stabel update
the cloud image can be retrived here https://getfedora.org/coreos/download?tab=cloud_operators&stream=stable
and the general openstack instuction are found here https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-openstack/
thse are really not targeted at magnum but rater makeing fedora core os avaiabel for other vms however you likely should
use those images if they are compatibale with magnum.
