The standard approach is:
On the machine of interest (virtual or non-virtual)
:; dmidecode -s system-uuid
On the host, when hosting a virtual machine:
: host; if ! test -r guest.uuid ; then uuidgen -r > guest.uuid ; fi
: host; qemu-system-x86_64 -uuid $(cat guest.uuid)
If that's not good enough, please clarify the question.
