i would like to know if anyone has run Linux containers on AWS EC2 instances (not in ECS) to know if that can actually work. as long as cgroups and namespaces are intact in the kernel built for these, i would think it should work fine. and i have no real reason to believe things a not intact (except for drivers for paravirtual support). my interest focuses on 64-bit kernels which is the direction AWS EC2 is going. one interest i have is to build an EC2 AMI that brings up a system with Amazon Linux and Ubuntu in containers.
also, i would like to know about doing this under the qemu or hercules VM engines, especially emulating non-amd64 architectures on amd64 hardware. i would think emulation should impose no issues, but i want to be sure; has anyone done this?
