Well, so much for libvirt support for stateful IPv6 addresses (dhcp6).
Not with the current design/implementation.
The problem is UPD6 server port 547 or rather how it is used. I am not
sure what the technical details are yet nor if this is "fixable", but as
the situation now stands, there can be only one dhcp6 server on a
system. DHCPD6 cannot live with dnsmasq and dnsmasq cannot live with
another dnsmasq ... first one started grabs the port and the others die
because they cannot get exclusive use.
I suppose you could run one dnsmasq which supported all virtual networks
but things are going to get messy when virtual networks are
started/destroyed/whatever.
I kludged together a little patch for libvirt which forced a dhcp-range
specification for any net with an ipv6 definition.
If anyone has some insight into this, I would appreciate hearing able it.
If anyone knew that you could not run two or more dhcp6 servers on the
same system, I realy wish that information was more widely known (or
obvious).
