I have been doing some testing and dnsmasq is capable of handling the
service currently provided by radvd. To implement this in dnsmasq
requires the following:
if an IPv6 dhcp-range is specified, then add:
enable-ra
if no IPv6 dhcp-range is specified, then add:
dhsp-range=<IPv6-subnet>,ra-only
Tested. The second one will work with basic dnsmasq-2.6.3. The first
one and dhcp-range itself only works with dnsmasq-2.64 (when released)
or dnsmasq-2.63+patches.
Since dnsmasq-2.48 does not support IPv6 dhcp but does handle IPv6 for
dns and CentOS 6 does include radvd, I also propose that a libvirtd.conf
option be added. If the option is not present or set off, then radvd is
used. If the option is set on, then dnsmasq is used.
I think this should rather be handled by configure script (perhaps with an
additional option if needed). Otherwise, I agree with the plan.
I can do that but then the individual backporting to (for example)
CentOS 6 with dnsmasq-2.48 would have to do nothing if DHCPv6 is not
wanted and, if DHCPv6 is wanted, to simply install dnsmasq-2.63+ and
change a libvirtd.conf parameter.
If the default is to use dnsmasq, then there are going to be mistakes
made. If the default is to use radvd, then many systems will not change.
