If I want to use SQL Server 2014 and availability groups and have a two logical processor vm, four nodes in total, only one being used in anger, I am correct in thinking that I need to license the vm hosting the primary replicas using 2 x 2 logical processors licensing packs ( min processors I can license for is 4 - or so I beleive ? ) and that providing I am not using any of the other instances in anger ( no backups, no report offloading etc ), the other instances only need to be covered by software assurance.
Could someone please confirm whether or not I am correct.
