I have been searching on the internet and could not find an answer to this question.
I understand that ephemeral disks lives until the VM is destroyed, but where are the ephemeral disks stored? On local host hosting the VM or in centralized storage (e.g. Ceph) or can I have both options?
If ephemeral can be stored on the same host the instance is running... what would happen if the host fails and the instance is migrated to another one? Will the ephemeral disk be moved across? Will the data persist?
Thank you very much
