Patch: https://github.com/openshift/console/pull/4964
Verified on CNV-2.3 latest as of May 06 2020. A RHEL-7 VM migrated and the SSH key name was passed correctly to the VM yaml: ssh_authorized_keys:. also after the migrated VM was powered ON, the ‘Authenticated SSH Keys’ content was set in /home/cloud-user/.ssh/authorized_keys, as expected.
