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. --Ed
