// of the VPC's security groups. You cannot link an EC2-Classic instance to more
// than one VPC at a time. You can only link an instance that's in the running
// state. An instance is automatically unlinked from a VPC when it's stopped - you
// can link it to the VPC again when you restart it. After you've linked an
// instance, you cannot change the VPC security groups that are associated with it.
// To change the security groups, you must first unlink the instance, and then link
// it again. Linking your instance to a VPC is sometimes referred to as attaching
// your instance.
