Public bug reported:

This is a bug in libvirt which has been fixed in upstream:
https://gitlab.com/libvirt/libvirt/-/issues/790

> When using qemu-pr-helper with multipath devices, the target devices
are not added to the domain's namespace as well as cgroups. As a result,
the sg_persist calls from the guest VM fail.

And the fix will be available in the next release (v11.6.0), but needs
to be backported to 22.04 and 24.04 as those are on 8.0.0 and 10.0.0
respectively.

I'm working on patch for 22.04 followed by 24.04
