dhcpv6 address advertised but vm not getting it

[Baodong (Robert) Li]

Launching a VM on a network with both ipv4 and ipv6. After the VM is booted successfully, login to it. Issuing ifconfig -a, no IPv6 address is configured. However, dnsmasq is running properly on the host and address for the VM has been advertised, which can be found from either the syslog msg or packet dump. Flushing ip6tables by 'ip6tables -F' and rebooting the VM, ipv6 address can be seen configured in the vm.

I am actually already working on this problem and have a patch available. After figuring out how to pass the unit test, I will push the patch soon.
