Public bug reported:
When launching an instance with one network interface and enabling 2
security groups everything is working as it supposed to be.
But when attaching additional network interfaces only the default
security group is applied to those new interfaces. The additional
security group isn't enabled at all on those extra interfaces.
We had to dig into the iptables chains to discover this behavior. Once
adding the rule manually or adding them to the default security group
everything is working fine.
