The launch command for qemu used is: QEMU_SDL_SAMPLES=3072 SDL_AUDIODRIVER=pulse QEMU_AUDIO_DRV=sdl qemu-system-x86_64 -enable-kvm -M q35 -m 4096 -cpu host -smp 6,sockets=1,cores=6,threads=1 -bios /usr/share/seabios/bios.bin -device ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1 -drive file=vm_image.img,id=disk,format=raw -soundhw ac97 The version of Qemu is: QEMU emulator version 2.2.0 (Debian 1:2.2+dfsg-5expubuntu9.4) This kernel has been custom built from commit 6ff33f3902c3b1c5d0db6b1e2c70b6d76fba357f on Linus' kernel repo, with only change being a patch that removes the 40-wire check on PATA controllers. Hardware has AMD-v as well IOMMU enabled. Motherboard is an ASRock 990FX Extreme 4 with an FX8350.
