migration/colo: make colo_incoming_co() return void

2024-05-22T20:34:31Z

Currently, it always returns 0, no need to check the return value at all. In addition, enter colo coroutine only if migration_incoming_colo_enabled() is true. Once the destination side enters the COLO* state, the COLO process will take over the remaining processes until COLO exits.

migration: Extend migration_file_set_error() with Error* argument

Use it to update the current error of the migration stream if available and if not, simply print out the error. Next changes will update with an error to report. Reviewed-by: Avihai Horon Acked-by: Fabiano Rosas Reviewed-by: Eric Auger Signed-off-by: Cédric Le Goater

migration: Remove block migration

2024-05-08T12:20:58Z

The block migration has been considered obsolete since QEMU 8.2 in favor of the more flexible storage migration provided by the blockdev-mirror driver. Two releases have passed so now it's time to remove it. Deprecation commit 66db46ca83 ("migration: Deprecate block migration").

migration: Add Error** argument to .save_setup() handler

2024-04-23T22:36:01Z

The purpose is to record a potential error in the migration stream if qemu_savevm_state_setup() fails. Most of the current .save_setup() handlers can be modified to use the Error argument instead of managing their own and calling locally error_report().
