/etc/ssh/sshd_config is supposed to be supported. That's the only supported way to alter the SSHD configuration without the changes getting overwritten in future updates.
I'll see with the team why it isn't (anymore?).
After trying a few more restores the other vms did not get this name change. Not sure why it happened to the one vm, but the other retained their original names and tags.
Du coup j'ai testé avec RHEL 9, ça fonctionne aussi.
Faut bien prendre l'iso "dvd", pas "boot" en revanche ! (je me suis fait avoir en téléchargeant l'image)
