Next problem: minimum RAM size. For instance, -M pc -m X, where X < 32KiB dies "qemu: fatal: Trying to execute code outside RAM or ROM at [...] Aborted (core dumped)" with TCG, and "KVM internal error. Suberror: 1" with KVM. Should a minimum RAM size be enforced? Board-specific? I'm inclined to declare this one a feature...
