Now I do not have machine for testing... But of course it is possible to test in VM too and it should be easy. Just create tun/tap interface for connection between VM and host. On host side start dnsmasq (which has support for RA & DHCPv6) and configure some non /64 prefix (e.g fd00::/100) [1]. And then check if NetworkManager in VM set correct /100 route (ip -6 route) and not some /64. Thats all.
[1] - example dnsmasq configuration (do not know if work, I just write what I remember): $ dnsmasq --enable-ra --dhcp-range=fd00::2,fd00::10,100,12h --interface=tun0 --except-interface=lo --listen-address=fd00::1 --bind-interfaces (host must have tun0 interface with ipv6 address fd00::1) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1254028 Title: [precise] network manager set incorrect /64 prefix from dhcpv6 client To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/1254028/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
