Subject: [PATCH v2 00/11] migration: Better error handling in rp thread, allow failures in recover
Date: Tue, 12 Sep 2023 18:21:34 -0400 [thread overview]
Message-ID: <20230912222145.731099-1-peterx@redhat.com> (raw)
v2:
- Patch "migration: Let migrate_set_error() take ownership"
- Fix three new call sites that uses migrate_set_error(), by dropping the
error_report_err() later on. [Fabiano]
- Patch "migration: Allow network to fail even during recovery"
- Fixed wrong check for dest QEMU
- Patch "migration: Allow RECOVER->PAUSED convertion for dest qemu"
- Newly added
- Patch "tests/migration-test: Add a test for postcopy hangs during RECOVER"
- Newly added, based on Fabiano's test case provided
v1: https://lore.kernel.org/r/20230829214235.69309-1-peterx@redhat.com
Again, if this collapse with anything I can rebase.
This series allow better error handling in the postcopy return path thread,
also it enables double-failures to happen during postcopy recovery, IOW,
one can fail again right during RECOVER phase on both sides.
Big thanks for Fabiano on prioviding a base test case for the double
failure case.
Please have a look, thanks.
