Starting with Igor's last version at
https://github.com/imammedo/qemu/commits/vmgen_wip , it's not clear to
me which changes need to be ported, which changes are obsoleted by
your new fw-cfg stuff and/or upstream churn in ACPI, device
properties, etc. In particular ACPI is still a total mystery to me,
though passing a single address from guest to host can't be that hard,
can it?

Any clues would be appreciated.
