[Pkg-libvirt-maintainers] Bug#994010: libvirt-daemon: cannot create lvm volume in logical pool if there is existing signature on that device

[Jonas L.]

Package: libvirt-daemon
Version: 7.0.0-3
Severity: important

Dear Maintainer,

I cannot create a LVM volume if there is an existing signature on that device.

This happen while trying to clone a VM or to create a new VM.

This bug has been comfirmed (https://bugzilla.redhat.com/show_bug.cgi?id=1940413) and
patched on upstream version 7.6
(https://gitlab.com/libvirt/libvirt/-/commit/d91a3e96c04ae093f4422b52e259750c86ba79fc).

I was unsure whether I should fill a bug report in order to backport a fix to stable.

A workaround is to run the lvcreate command manually. But it is a nightmare when cloning a VM, as you need
to create the new volume to wipe it, and remove it to clone the orignal disk.
