Please read the UUID generation algorithm.

Maybe you have to define entropy. For human consumers, "Paolo Bonzini <pbonzini@redhat.com>" has considerably less "entropy" than 8aacc35ffca0d34fccf8a750e84e3a81bdcb940b, as does even "Paolo Bonzini <bonzini@gnu.org, pbonzini@redhat.com>". For non-human consumers, a good mailmap will do.

I am not alone.
