Current DEFAULT_RAM_SIZE(128MB) enforced by QEMU would not work for all machines. Introduce a default_ram_size as part of MachineClass.
The below patches has following behaviour: 1) If the user does not provide "-m" option, machine's default ram size will be picked. 2) In case the user provides memory that is lesser than machine's default ram size, we upscale the ram_size to machine's default_ram_size. A warning is displayed for the change that qemu has done. On the side note, there are other cleanup of removing ram_size, slots and maxmem from vl.c. All these are being parsed by generic code. This can be moved to machine specific property. I will take a stab at it next.
