[Qemu-devel] virtio-blk io bar size changed

[Dr. David Alan Gilbert]

Hi,
  Lukáš reported that there's a migration breakage between 3.1 and
current head with virtio-blk;   it looks like the io bar changes from 64
to 128 bytes and my bisect suggests it's:

commit caa1ee43131c060347b32893abd41fe4865eaa2e (HEAD, refs/bisect/bad)
Author: Changpeng Liu <address@hidden>
Date:   Wed Jan 16 13:19:30 2019 +0800

    vhost-user-blk: add discard/write zeroes features support


How do we fix that?

Dave
