Sangeetha Hariharan updated CLOUDSTACK-1488:
--------------------------------------------
Description:
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.
I am not sure about the exact steps that leads to this issue. I dont see this
problem with other Vms.

> 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.
> I am not sure about the exact steps that leads to this issue. I dont see this
> problem with other Vms.
