Subject: [Qemu-devel] [PATCH v3 2/4] tests/test-replication.c: Add test for ignoring requests after failover
Date: Tue, 3 Sep 2019 11:20:29 +0200 [thread overview]
Message-ID: <b9383e7b7697ec1f1eb963449d14f2e44724b907.1567500411.git.lukasstraub2@web.de> (raw)
In-Reply-To: <cover.1567500411.git.lukasstraub2@web.de>
This simulates the case that happens when we resume COLO after failover.
Signed-off-by: Lukas Straub <lukasstraub2@web.de>
