Couldn't we do some sort of hash on the image path+filename? So same
image starts always with same MAC, different images -> different mac
adresses. I guess I am supposed to post this suggestion on the qemu

PS: Other topic, I still wonder how a guest can bevahe totally different
on networking (unable to use network) when macaddr is set by kvm
parameters? For me this sounds like a bug, not?
