https://bugzilla.kernel.org/show_bug.cgi?id=202055 --- Comment #26 from Dongli Zhang (dongli.zhang@xxxxxxxxxx) --- Hi Alex, The patch does not work for me :( Here is how I reproduce the issue. The attached file is my kernel config. qemu commit: 6f2f34177a25bffd6fd92a05e6e66c8d22d97094 linux commit: 1c7fc5cbc33980acd13d668f1c8f0313d6ae9fd8 To build qemu: # ./configure --target-list=x86_64-softmmu # make -j8 > /dev/null To build linux: use the attached config # make -j8 > /dev/null To reproduce, boot into the linux kernel. I always use qemu at where it is built. I do not run "make install" for qemu. # modprobe vfio # modprobe vfio-pci # echo 0000:01:00.0 > /sys/bus/pci/devices/0000\:01\:00.0/driver/unbind # echo "8086 f1a6" > /sys/bus/pci/drivers/vfio-pci/new_id # ./x86_64-softmmu/qemu-system-x86_64 -hda /home/zhang/img/ubuntu/disk.img -smp 2 -m 2000M -enable-kvm -vnc :0 -device vfio-pci,host=0000:01:00.0 # ./x86_64-softmmu/qemu-system-x86_64 -hda /home/zhang/img/ubuntu/disk.img -smp 2 -m 2000M -enable-kvm -vnc :0 -device vfio-pci,host=0000:01:00.0 WARNING: Image format was not specified for '/home/zhang/img/ubuntu/disk.img' and probing guessed raw.
