[Bug 1945196] [NEW] cloud-init regenerating ssh host keys on Azure
Public bug reported:
cloud-init fails in "crawl_metadata" phase in first boot of Ubuntu 20.04
VM on Azure cloud. After few reboots, the cloud-init succeeds in "crawl
metadata" phase and it then regenerates the ssh host keys. The
communication between hosts of the cluster is broken thereafter, and
cluster formation fails. Changing host keys in general is an issue, and
should be avoided. Expected behavior: if the cloud-init succeeds in
later reboots, it shouldn't regenerate host keys.
** Affects: cloud-init
Importance: Undecided
Status: New
** Attachment added: "cloud-init.log"
