Description Fam Zheng 2017-05-18 05:25:11 EDT

We should have

fc0932f block: Reuse bs as backing hd for drive-backup sync=none

which fixes a latent bug in (QMP) drive-backup sync=none, that stale data might be read from the target image.

Comment 2 Miroslav Rezanina 2017-05-23 04:16:11 EDT

Fix included in qemu-kvm-rhev-2.9.0-6.el7
