Description

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.
