I wouldn't make it QEMU specific. It should probably go into libvirt.conf, 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. Once that would be done, we could show the UUID via 'virsh capabilities' so management software can find it. If above doesn't sound right, then providing it via the XML in vsi is probably the way to go.
