issues during fresh install with libvirt

After reinstalling an arch machine and then installing libvirt, I had some funny errors like:

Error starting network 'default': internal error: Failed to apply firewall rules /usr/bin/iptables -w --table filter --insert LIBVIRT_INP --in-interface virbr0 --protocol tcp --destination-port 67 --jump ACCEPT: iptables: No chain/target/match by that name.

After installing `dmidecode` things starting acting normally again:

Just previous to this (while libvirt default network was still not working) I had also installed `ipset`, as `systemctl status libvirtd` had a complaint about it missing (though that may not be fatal).

In conclusion, it seem that `dmidecode` at least is essential for libvirtd to start and should be a requirement?  Or is there something else amiss here?
