The default for 64bit is 32GB, which is the reason that m2.4xlarge instances only report this amount of memory. Fix: Setting this limit to 70GB as there is a known restriction for t1.micro instances at about 80GB. Testcase: Booted m2.4xlarge with this set to 32GB shows 32GB of memory, when set to 70GB, it correctly reports 68GB. Booted a t1.micro as well to verify this has not caused problems there. --- The following is copied from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/651370/comments/14 . I'm fairly sure that The problem is also with a stock image (without the additional command line options suggested in that bug). Brandon's and Scott's workaround works for me partly, but the kernel on an instance started in such a way seems to detect only 32 GB of memory even for a m2.4xlarge instance which should have 68.4 GB available, according to the EC2 instances page. Is this a side-effect of the workaround, or a completely separate bug?
