I want my VMs to be assigned static addresses by hostname. I would
prefer to set up a generic way to configure dnsmasq, since I don't think
this is the last thing I'll want to change about address assignment.
I saw this patch from "Mads Chr. Olesen"
https://www.redhat.com/archives/libvir-list/2008-April/msg00327.html
But it seems like a lot of work to give access to only one dnsmasq
option.
I'm working on a patch that enables a dnsmasq.d directory where you can
(optionally) put individual configuration files. I have not fully tested
it yet, so please don't consider this an official submission.
I also don't feel that I have spent enough time with the code to
understand the 'philosphy' if you will, the guiding attitudes. Is the
all-XML approach better according the libvirt developer community
standards? If so, why?
Thanks. Untested patch follows. Please let me know if I'm on the right
path and if not, why.
