I need three network interfaces in one instance for my work.By default there is one eth0 but I want to add eth1 and eth2 in an instance.
I created network interfaces using the same security rule that I used to create the EC2 instance in zone us-west-2a and my instance is also in this zone us-wes-2a
My instance type is t2.micro
now i choose the instance options and choosing the instance where i want to add ,then from actions ->networking->attach network interface gives this error
No available network interfaces were found for this VPC or availability zone
Could someone guide me to resolve this issue? thanks a lot.
