[libvirt-users] Assigning IPv6 address to guest

Hello, I am trying to assign an IPv6 address to one of my guests. I followed the following guide, unsuccessfully: https://www.berrange.com/posts/2011/06/16/providing-ipv6-connectivity-to-... . I have the following config files: dumpxml of the guest `deb`: http://sprunge.us/iUef net-dumpxml of network `default`: http://sprunge.us/WTfH net-dumpxml of network `ip6`: http://sprunge.us/YEXc Host: ifconfig: http://sprunge.us/cJOg Routing table: IPv6: http://sprunge.us/GChZ IPv4: http://sprunge.us/dACN /etc/network/interfaces: http://sprunge.us/fHcf /var/lib/libvirt/radvd/ip6-radvd.conf: http://sprunge.us/JcfF ip6tables: http://sprunge.us/JGBG uname -a: http://sprunge.us/acFF Guest: ifconfig: http://sprunge.us/JIFN Routing table: IPv6: http://sprunge.us/ZPfT IPv4: http://sprunge.us/gbXA /etc/network/interfaces: http://sprunge.us/ZaBB uname -a: http://sprunge.us/CFFL Both machines are running Debian Wheezy. virsh version is 0.9.12.3. The IP address I'm trying to assign to the guest is "2607:5300:60:1156::2/64". Forgive me if I'm making some trivial mistake, but this is more or less the first time I'm productively using IPv6. Thanks
