Subject: [Qemu-devel] [PATCH 0/3] Block migration when streaming block jobs are running
Date: Fri, 20 Jul 2012 21:32:34 +0200 [thread overview]
Message-ID: <1342812757-2651-1-git-send-email-benoit@irqsave.net> (raw)
From: Benoît Canet <benoit@irqsave.net>
This patchset is designed to avoid starting a live migration while one or more
streaming block jobs are running.
Tested with the following sequence:
QEMU 1.1.50 monitor - type 'help' for more information
(qemu) block_stream virtio0 1k
(qemu) migrate tcp:localhost:4444
migrate: Streaming blocks migration
(qemu) migrate tcp:localhost:4444
migrate: Streaming blocks migration
(qemu) block_job_cancel virtio0
(qemu) migrate tcp:localhost:4444
migrate: Connection can not be completed immediately
(qemu)
=> migration then succeed
Benoît Canet (3):
block: Add bdrv_have_block_jobs() so migration code abort if needed.
qerror: Add error telling that streaming blocks migration
migration: block migration when streaming block jobs are running.
block.c | 14 ++++++++++++++
block.h | 2 ++
migration.c | 5 +++++
qerror.c | 4 ++++
qerror.h | 3 +++
