Public bug reported:
I try to passthrough my Intel GPU with this command:
qemu-system-x86_64 -nodefaults -parallel none -k de -rtc base=localtime
-serial unix:/run/qemu/win7-serial.sock,server,nowait -monitor
unix:/run/qemu/win7-monitor.sock,server,nowait -netdev user,id=net0

linux,id=kbd1,evdev=/dev/input/by-path/pci-0000:00:1a.0-usb-0:1.2.2:1.2

linux,id=mouse1,evdev=/dev/input/by-
path/pci-0000:00:1a.0-usb-0:1.2.2:1.2-event-mouse -enable-kvm -cpu host

virtio-blk-pci,drive=boot,bootindex=1 -drive
file=/opt/vm/qcow2/win7.qcow2,format=qcow2,if=none,id=boot
This ONLY works if i remove "-enable-kvm" else the windows (7 and 10)
boot crashes in bluescreen "stop 0x0000003b" (probably while loading the
intel gpu driver (intel graphics 3000).
The system is an older ThinkPad T420 with Intel(R) Core(TM) i5-2520M CPU
@ 2.50GHz.
