I pass through Intel Corporation HD Graphics 530, an IGD card to windows 7 vm by legacy mode, in fedora 25(kernel=4.8.6, qemu=2.7). I can see windows output on the screen successfully, but always confused graphic during booting and low resolution (640*480) when running. After installation of driver downloaded from Intel official website, nothing improved, and the driver show error code 43.
>From the view of driver, what’s the difference between an original, physical IGD and a passed through IGD? Any functions disappeared? What should I do to correct the error？ Or there’s another version of driver？
