Set up DHCP server IPv6 on Ubuntu 14.04

[Reed Xia]

Hello all,

I have a Ubuntu 14.04 with 2 Ethernet adapters(eth0 and eth1), eth0 is
connected to an homeware device, I need set up DHCP IPv6 service against
eth0(I set the IPv6 address for eth0 as 2007::7/64 in Ubuntu), and I want
the homeware to obtain a fixed IPv6 address(2001::10), so I did it in
following way, now the problem is the homeware always cannot get IPv6, I
can see message "Unable to pick client prefix: no IPv6 pools on this shared
network" from dhcpd service, I guess the dhcpd6.conf have some problem, can
you please help figure out?
