Sangeetha Hariharan commented on CLOUDSTACK-1481:
-------------------------------------------------
In this case , Vm is part of 1 ipv6 network and 1 ipv4 network.
create a dual stack network N1 -domain name- hello1383
create a ipv6 network N2 -domain name- yoyo1372
Deploy a 2 Vms in N1 and N2.
>From 1 VM, try to access other VM using its fully qualified domain name.
Accessing using N1's domain name succeeds. But access using N2's domain name
fails.

> Components: Management Server

> IPV6 - When Vm is part of 1 dual network and 1 ipv6 network , name resolution
> using fqdn fails for the ipv6 network.
> Steps to reproduce the problem:
> create a dual stack network N1.
> create a ipv6 network N2.
> Deploy a 2 Vms in N1 and N2.
> From 1 VM, try to access other VM using its fully qualified domain name.
> It fails.
> I see the domain name of N2 is not being programmed in /etc/resolv.conf.
> Only the domain name of N1 is programmed.
