Yes, I agree that those are the general assumptions, but sometimes there
are exceptions or rare cases, and I simply asked, but apparently, what I
was trying to get is not possible. And that's ok.
I tried to set up client-id but still mac-address seems to have preference,
and I cannot force all

There are much smarter people than me here, but if I might chime in:
Two basic assumptions in networking are that no two separate devices will
share the same MAC address, and a device's MAC address doesn't change after
it's manufactured. Obviously there are practical exceptions (spoofing, privacy

I never talked of VM on purpose, because they are not VM (hence, no
hypervisor or any other controller plane). Indeed I talked of live linux
distributions running on USB that I only use for very specific tasks, and
of course, I run them over physical machines, but these physical
machines are
Virtual machines usually generate their own MAC addresses for their virtual
network cards in bridge mode. So the MAC would be the identifier. They don’t
share a MAC address with the host itself.

The unique MAC address
so, if I have two virtual computers running over the same hardware, what
should be used as identifier for dnsmasq? the physical mac-address (just
one, as it is just one physical card)? the dhcp-client-id or hostname
(configurable as per logical device level)?
That's exactly my point, that there

Not an answer, actually.

that's not possible in this case, but moreover, there might be other
scenarios where it wouldn't be possible either.
