The mirroring command I see from dev-scripts is:
oc adm release mirror --insecure=true -a /opt/dev-scripts/pull_secret.json --from registry.ci.openshift.org/ocp/release:4.11.0-0.nightly-2022-07-13-131410 --to-release-image virthost.ostest.test.metalkube.org:5000/localimages/local-release-image:4.11.0-0.nightly-2022-07-13-131410 --to virthost.ostest.test.metalkube.org:5000/localimages/local-release-image
Shouldn't there be an entry for registry.ci.openshift.org?

Yes there should be an entry for registry also, added it.

ssh "${ssh_opts[@]}" "echo '125.12.15.16 registry.ci.openshift.org' | sudo tee -a /etc/hosts "
done
