Description of problem: ---------------------- There is one dnsmasq configuration file per network in /var/lib/libvirt/dnsmasq, bypassing the global dnsmasq config file located in /etc/dnsmasq.conf. The latter allows the definition of any DHCP option to be sent to the querying client(s), such as boot file name, TFTP server address, and so on... These options can be sent according to specific tags and client-ids. Unless I'm missing something (maybe the wiki is not up-to-date or does not go deep enough at https://libvirt.org/formatnetwork.html), the last libvirt version (3.5.0) does not offer those possibilities.
In /etc/dnsmasq.conf, the corresponding keywords are: - dhcp-host which can be used to set a tag per client-id - dhcp-option to define a requested option for clients matching a tag - dhcp-option-force to send a non-requested option for clients matching a tag
