With Ubuntu Xenial you can remove /etc/machine-id when cloning the
system and it will be re-created with a new unique value on first boot.
Similarly once systems are running you can remove the file and reboot.
See machine-id(5) man page.
Otherwise as Steinar says add
ignore-client-uids true;
dhcpd.conf(5) man page will contain details if it is valid in your
version.
