Does libvirt need to do anything special to its generated yes, right now its specified as -M pc_q35 > command line to specify the old vs. the new machine model? > The current command line I'm using something such as: $ /usr/local/bin/qemu-system-x86_64 -name "f16" -M pc_q35 -m 1G -smp 4 -hda ./f16.img --enable-kvm -bios /q35-seabios/out/bios.bin -acpitable file=/q35-seabios/out/q35-acpi-dsdt.aml -monitor stdio So it might be nice to avoid the '-acpitable' flag. Perhaps, we can teach qemu to pull in the correct acpitable depending on the -M specification... Thanks, -Jason
