Fix For: 4.1.0
Ipv6 - When Vm is deployed as part of multiple networks, sometimes one of the
IPV6 address assigned to guest VM is lost.
I have a Vm that is part of a dual network and ipv6 network.
I had IPV6 addresses assigned to eth0 and eth1 network.
After about 2 hours , when i logged in to the same Vm , I see that the ipv6
address of eth0 is lost.
