Description of problem:

I have marked this urgent as this should be working and today is world IPv6 day.

My network is defined as follows:

<network>
  <name>TheCommons</name>
  <uuid>....</uuid>
  <forward mode='route'/>
  <bridge name='virbr0' stp='off' delay='0' />
  <ip address='10.0.1.1' netmask='255.255.255.0'>
  </ip>
  <ip family='ipv6' address='fd00:xxxx:xxxx:1::1' prefix='64'>
  </ip>
  <ip family='ipv6' address='2001:xxxx:xxxx:0::1' prefix='64'>
  </ip>
</network>

That didn't automatically add any of the ipv6 addresses. As I said, no
radvd. If I read the bug reports correctly, it is supposed to be automagic.

Looking at the systclts mentioned here:  https://bugzilla.redhat.com/show_bug.cgi?id=501934, the sysctls are set exactly as said they would be in that bug.

I see others on the mailing lists saying their configurations work, but they are all bridges to physical devices. So, the problem may be specifically to virtual bridge setups.
