OK, as far as I am concerned, the critical thing is what parameters will work with dnsmasq-2.48 so that if libvirt-1.0.0 was rebuilt and installed on (for example) CentOS 6.3, that dnsmasq-2.48 will work.

First of all, at a minimum, to support DHCPv6, you must be running dnsmasq-2.64 or dnsmasq-2.63+patches [those patches may fit on earlier versions of dnsmasq, I have no idea]. But, if you do not specify any DHCPv6 but just the regular IPv4 stuff plus listen-address=<IPv6-address>, will dnsmasq work with the changes I have made to libvirt that puts the dnsmasq parameters into a conf-file.

I am in the process of creating a CentOS 6.3 virtual system. I will then feed the dnsmasq on that system slightly modified versions of various conf-files created under libvirt to see which are going to give dnsmasq indigestion.

I still believe that for someone to go to the effort of getting (lets say) libvirt-1.0.0 built, installed and running on CentOS 6.3, then requiring that dnsmasq-2.64 also be installed is not that big a deal ... but that is just my opinion.
