That's an irrelevant question for the libvirt XML format. We're simply
defining what MAC address a guest has. Its upto the underlying virtualization
technology to do the neccessary mac address spoofing protection based on
the define MAC libvirt assignes to a guest

It doesn't. Libvirt does not provide policy, only mechanism. Its upto
tools using libvirt to ensure uniqueness.

Again, not libvirt's problem. Its the underlying virt technology to deal
with.
