For Arm embedded boards we mostly tend to "restrict the user to what you can actually do", except for older boards where we tended not to write any kind of sanity checking on CPU type, memory size, etc.
If we're going to strictly limit memory size that's accepted I wonder how we could information users/mgmt apps about what's permitted?
For users, we inform them by exiting with a hopefully informative error message. Management apps presumably need to know already because they would want to avoid presenting the guest with weird configs that the guest OS might or might not cope with, even if QEMU accepted them. -- PMM
