[Bug 862136] Re: Can't define network with IPv6 address in libvirt - fails to define address

[Neil Wilson]

You might want to try setting the dummy interface up in libvirt. That
may workaround it for now at the expense of polluting the ifconfig
listings.


** Patch added: "Start dummy bridge interface 'up' rather than 'down'"
   https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/862136/+attachment/2480654/+files/Bring-up-dummy-interface.patch

** Tags added: apport-collected running-unity

** Description changed:

  When defining a network with an IPv6 address, libvirt fails to allocate
  the address properly and the launch of the supporting dnsmasq processes
  fails.
