[Bug 2044235] [NEW] nova-condutor put instance in error during live-migration due to remote error MessagingTimeout
Public bug reported:
Description
===========
Nova-conductor put instance in error if the exception is not know in _build_live_migrate_task during the live-migration. [1]
The exception come from _call_livem_checks_on_host and we can see raise exception.MigrationPreCheckError if we facing to messaging.MessagingTimeout. [2]
The function check_can_live_migrate_destination do a check also on souce host with check_can_live_migrate_source [3] and this check can also return MessagingTimeout and this one is not catch properly because it's a remote "Remote error: MessagingTimeout" due to dest host try to
contact source host and this source host not reply.

Expected result
===============
The live-migration task are in pre check so we need to have instance in Active state with migration task in error
Actual result
=============
The instance in ERROR state and the migration is in error
Environment
===========
I have reproduce the issue on devstack multinode with default config

Expected result
===============
The live-migration task are in pre check so we need to have instance in Active state with migration task in error
Actual result
=============
The instance in ERROR state and the migration is in error
Environment
===========
I have reproduce the issue on devstack multinode with default config
