Hi. First of all thanks for this great project and specially
for keeping the Perl library.
I need to keep the IP address of the virtual machines the same
as long as possible. dnsmasq provides a setting for lease time.
It can be set to infinite, but not from within libvirt.
I found this patch from 2016.

But it looks like it never made to libvirt.
That particular patch no, but another approach did:
https://gitlab.com/libvirt/libvirt/-/commit/97a0aa246799c97d0a9ca9ecd6b4fd932ae4756c
It's part of the v6.3.0 release.
Some time ago I made it work changing dnsmasq/default.conf.
Then we made it immutable with chattr. This no longer works
because libvirt refuses to start dnsmasq unless it can write
to it. Fair enough.
I've seen I can add manual IP addresses as stated here:
https://wiki.libvirt.org/page/Networking
This is ok, but it would be a considerable amount of work,
requiring lots of manual labour.
Is there a way to set the lease time from libvirt ?
Well, if you don't really need static IPs but a stable way to address
guests, then NSS plugin might help:
