It looks okay to me. Can you provide an Acked-by from one of the qemu or kvm maintainers?
Is CMOS the best place to communicate this (as opposed to fw_cfg)?
I know we currently expose memory size via CMOS but perhaps it's better to switch to a 64-bit fw_cfg value.
I'd personally prefer fw_cfg.
Also, another possibility would be to stop sending an absolute max and to instead send a map of memory. The latter would allow for non-contiguous memory.
That would be highly useful for testing purposes.
