I am attempting to deploy a Fedora 14 AMI built with BoxGrinder (Build 0.9.1) using the Amazon m2.4xlarge instance. The specifications for the m2.4xlarge image include 68.4 GB of memory. However, upon bootup, the instance only recognizes half of the stated memory. I am sure that the visible memory is being limited by the CONFIG_XEN_MAX_DOMAIN_MEMORY kernel configuration parameter; the default value is 32 (https://forums.aws.amazon.com/thread.jspa?messageID=246488). Is it possible to change this value during the EC2 image creation using BoxGrinder? Or is my only option to recompile the kernel after deployment?
