qemu-system-aarch64: Requested ram size is too large for this machine: maximum is 1GB
(Note that the maximum is 1GB, not 4GB -- it's just that values between 1 and 4GB happened not to make QEMU crash, though it wouldn't handle them very usefully before.)
I've submitted a patch to the list: http:// patchwork. ozlabs. org/patch/ 1067963/
With it, QEMU will give this error instead:
