well, harmless….though for a good reason we stopped pulling in “libvirt” as the metapackage brings problematic deps in certain cases (iirc it was due to ppc64le)
That’s why we depend on exactly just
libvirt-daemon-config-nwfilter libvirt-daemon-kvm libvirt-lock-sanlock libvirt-client libvirt-python

As Francesco says it’s mostly harmless, it’s just that on a truly clean environment “libvirt” wouldn’t be installed

Thanks,
