Public bug reported:
Live-migration monitoring is based on the memory migration only. Which
means that if a live-migration is taking a long time to migrate a disk,
only the live_migration_progress_timeout parameter will be taken into
account and will supersede the live_migration_completion_timeout
parameter. In other words, because live_migration_progress_timeout is
logically smaller than live_migration_completion_timeout, the later will
never be used except in a case where the disk migration is fast and the
memory migration is slow.
Steps to reproduce:
- live-migrate an instance with lots a data on its ephemeral disk
- observe that the live-migration is aborted because of
live_migration_progress_timeout only.
