kvmgt local display don't take effect

[Yuan, Hang]

I don't see any problems on your configuration based on my knowledge. Would you like to try a Linux guest? If Linux guest can work, it means GVT is fine. Then the problem might be Windows guest is not configured correct to use Intel gfx device for display.

Regards,
Henry

Do you use seabios in "-bios /usr/bin/bios.bin'? The local display only works on seabios now.

Reply:

I Sure the bios is seabios now;



#!/bin/bash

/usr/bin/qemu-system-x86_64 \

    -m 2048 -smp 2 -M pc -cpu host\

    -name local-display-vm \

    -hda /root/kvmgt/win7.qcow2 \

    -L /root/igvtg-qemu/roms/seabios/out \

    -bios /root/igvtg-qemu/roms/seabios/out/bios.bin -enable-kvm \

    -net nic,macaddr=52:54:00:10:00:1A -net tap,script=/etc/qemu-ifup \

    -vga none \

    -display gtk,gl=on \

    -k en-us \

    -machine kernel_irqchip=on \

    -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 \

    -cpu host -usb -usbdevice tablet \

    -device vfio-pci,sysfsdev=/sys/bus/pci/devices/0000:00:02.0/0aa0edee-9f5e-11e7-8864-4f7957d97b7c,x-display=on,x-igd-opregion=on



but on qemu display also "Guest has not initialized the display (yet)"
Best Regards!
