I wouldn't make it QEMU specific. It should probably go into

but then libvirt.conf would need to be modified on every machine when installed. How should the code react if no valid UUID is found in the config file? Create a temporary one that changes with every restart of libvirt? Also dmidecode should probably be used on those machine where it returns a valid UUID.
How do we decide that dmidecode is showing a valid UUID though. Is a UUID of all 0's, all 1's or all F's valid ?
With high probability, 32 hex chars that are the same can probably be considered 'wrong'. Some details on how one could handle the different cases of valid/invalid UUIDs: libvirtd.conf dmidecode handling valid UUID valid UUID libvirtd.conf UUID overrides dmidecode's UUID invalid UUID invalid UUID generate a temporary one; new one after libvirtd restart valid UUID invalid UUID use valid UUID invalid UUID valid UUID use valid UUID Stefan
