+    The tripleo-ssh-known-hosts ansible role used the list of network names to
+    create the different possible hostnames in the ssh_known_hosts file. The
+    network names do not match the actual network hostnames, like internal_api
+    vs. internalapi which results in ssh host verification to fail and e.g.
+    live migration to fail.
+
+    Initial approach in a5bcbc8d015b792b3546ecbb139506f248dacfe8 had to be
+    reverted as it resulted in errors when the _hostname inventory information
+    was missing from the ansible inventory.
+
+    This syncs to use the same approach to create the hostname like in
+    https://review.opendev.org/693010 to have entries in /etc/hosts and
+    ssh_known_hosts created in the same way/source.
