The 'virt-aa-helper' process gets a XML of the VM it needs to create a profile for. For a disk type='volume' this XML contained only the pool and volume name. The 'virt-aa-helper' needs a local path though for anything it needs to label. This means that we'd either need to invoke connection to the storage driver and re-resolve the volume. Alternative which makes more sense is to pass the proper data in the XML already passed to it via the new XML formatter and parser flags. This was indirectly reported upstream in https://gitlab.com/libvirt/libvirt/-/issues/546 The configuration in the issue above was created by Cockpit on Debian. Since Cockpit is getting more popular it's more likely that users will be impacted by this problem.
