Abiquo 3.8.1 supports multiple IP addresses in the AWS integration. You can synchronize existing virtual machines with multiple IP addresses and create multiple IP addresses through Abiquo, including multiple Elastic IPs. In previous versions Abiquo supported one elastic network interface with one private IP address and one elastic IP address per instance.
Abiquo 3.8.1 supports the number of IP addresses supported by the AWS hardware profile (instance type). See http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html#AvailableIpPerENI
Now if the user adds multiple IPs in the same subnet, Abiquo adds them to the same elastic network interface. And if the IPs are in a different subnet, Abiquo adds them to a different elastic network interface. For information about Elastic Network Interfaces, see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html
