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!
