Public bug reported:
The live_migration_downtime, live_migration_downtime_steps and
live_migration_downtime_delay default values are not honored.
Those parameters tune the live-migration abortion and must be higher
than the LIVE_MIGRATION_DOWNTIME_MIN, LIVE_MIGRATION_DOWNTIME_STEPS_MIN
and LIVE_MIGRATION_DOWNTIME_DELAY_MIN minimum values.
However, those parameters have default values that are higher than the
minimum values but they are overridden by the minimum ones.
Steps to reproduce:
- live-migrate an instance
- simulate a downtime
- observe that the minimum values are used instead of the default ones.
