[Pkg-libvirt-maintainers] Bug#981001: hot-attach fails for qcow files with backing chain

[Christian Ehrhardt]

Package: libvirt
Version: 6.9.0-4

Hi,
as reported to upstream in [1] use cases with snapshots or base-images
that use qcow files
with a backing chain will fail to hot attach e.g. via `virsh
attach-device`. Details and steps to reproduce in [1].

The reason is that apparmor in libvirt does not iterate over those
backing chains which was fixed in [2]. I'd ask to fix/avoid this issue
by applying that change for the most recent Debian version.
