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
