Subject: [Qemu-devel] [PATCH 0/3] Show files ancestors count in HMP
Date: Mon, 23 Jul 2012 16:56:52 +0200 [thread overview]
Message-ID: <1343055415-24767-1-git-send-email-benoit@irqsave.net> (raw)
From: Benoît Canet <benoit@irqsave.net>
In some setups many backing files and snapshot are chained.
This lead to the formation of huge trees of snapshots all depending
on a common ancestor.
Hence if something bad happen to this common ancestor all the snapshot
of the tree will be broken.
This patch add an easy way for the user to monitor backing file ancestors
count and take the good decision (streaming).
Benoît Canet (3):
block: Add bdrv_are_busy()
qerror: Add error telling that block dev usage prevents migration
migration: block migration when any of the block device is busy
block.c | 13 +++++++++++++
block.h | 2 ++
migration.c | 5 +++++
qerror.c | 4 ++++
qerror.h | 3 +++
