According to the dnsmasq manpage, the netmask for IPv4 address ranges will be auto-deteremined from the interface dnsmasq is listening on, but it can't do this for IPv6 for some reason - it instead assumes a network prefix of 64 for all IPv6 address ranges. If this is incorrect, dnsmasq will refuse to give out an address to clients, instead logging this message:
dnsmasq-dhcp[2380]: no address range available for DHCPv6 request via virbr0
The solution is for libvirt to add ",$prefix" to all IPv6 dhcp-range arguments when building the dnsmasq.conf file.

ACK, and I confirmed it fixes things for me too Thanks, Cole
