Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Text:
.SSH keys are now generated correctly on EC2 instances created from a backup AMI Previously, when creating a new Amazon EC2 instance of RHEL 8 from a backup Amazon Machine Image (AMI), `cloud-init` deleted existing SSH keys on the VM but did not create new ones. Consequently, the VM in some cases could not connect to the host. This problem has been fixed for newly created RHEL 8.5 VMs. For VMs that were upgraded from RHEL 8.4 or earlier, you must work around the issue manually. To do so, edit the `cloud.cfg` file and changing the `ssh_genkeytypes: ~` line to `ssh_genkeytypes: ['rsa', 'ecdsa', 'ed25519']`. This makes it possible for SSH keys to be deleted and generated correctly when provisioning a RHEL 8 VM in the described circumstances.
