Subject: [Qemu-devel] question：a question about throttle and hot-unplug
Date: Thu, 14 Sep 2017 17:41:40 +0800	[thread overview]
Message-ID: <59BA4ED4.6070108@huawei.com> (raw)

Hi, Kevin

the patch you commited: https://github.com/qemu/qemu/commit/7ca7f0f6db1fedd28d490795d778cf23979a2aa7#diff-ea36ba0f79150cc299732696a069caba

remove blk_io_limits_disable from blk_remove_bs

Then, if a disk which configured qos hot-unplug from VM, the backend of the disk reminds in throttle group.

So when I hot-unplug and hot-plug a disk, and use the same throttle group name, will lead to qemu crash.


and Eric committed a path as fallow fixed the bug on qemu-kvm 2.9.0-rc4:
https://github.com/qemu/qemu/commit/1606e4cf8a976513ecac70ad6642a7ec45744cf5#diff-7cb66df56045598b75a219eebc27efb6


Is what I said as below correct? I just want to make sure it. Thank you :）
