Chapter 3. Managing certificates
Red Hat Virtualization Manager uses certificates to enable encrypted communications. These RHV certificates follow a standard 398 day lifetime and must be renewed once per year.
Do not let certificates expire. If they expire, the environment becomes non-responsive and recovery is an error-prone and time-consuming process.
Starting in RHV 4.4, you will receive warning notifications 120 days before expiration and error notifications 30 days before expiration. Do not ignore these notifications. For information on renewing certificates, see Renewing certificates before they expire in the Administration Guide.
