ryzen 2700x

MSI RADEON RX 570 8GB


all following commands successfully run guest operating system

qemu-system-x86_64.exe -hda d:\QEmu\mint-cinnamon -boot c -m 4096 -accel
whpx -smp 8,sockets=1,cores=8,threads=1

qemu-system-x86_64.exe -hda d:\QEmu\mint-cinnamon -boot c -m 4096 -accel
whpx,thread=multi -smp 8,sockets=1,cores=8,threads=1

qemu-system-x86_64.exe -hda d:\QEmu\mint-cinnamon -boot c -m 4096 -machine
type=pc,accel=whpx, -smp 8,sockets=1,cores=8,threads=1

Windows Hypervisor Platform accelerator is operational


but I tried four more commands to try video card acceleration through the
virtio driver

qemu-system-x86_64.exe -hda d:\QEmu\mint-cinnamon -boot c -m 4096 -machine
type=pc,accel=whpx, -smp 8,sockets=1,cores=8,threads=1 -vga virtio -display
sdl,gl=on

qemu-system-x86_64.exe -hda d:\QEmu\mint-cinnamon -boot c -m 4096 -machine
type=pc,accel=whpx, -smp 8,sockets=1,cores=8,threads=1 -vga virtio -display
gtk,gl=on

qemu-system-x86_64.exe -drive file=d:\QEmu\mint-cinnamon,if=virtio  -boot c
-m 4096 -machine type=pc,accel=whpx, -smp 8,sockets=1,cores=8,threads=1
-vga virtio -display sdl,gl=on

qemu-system-x86_64.exe -drive file=d:\QEmu\mint-cinnamon,if=virtio  -boot c
-m 4096 -machine type=pc,accel=whpx, -smp 8,sockets=1,cores=8,threads=1
-vga virtio -display gtk,gl=on

and all it results

qemu-system-x86_64.exe: OpenGL support is disabled


At this time, version, is it possible to enable OpenGL virtio driver on
qemu under windows host for graphics acceleration on the guest linux?

if possible, how to enable OpenGL support for QEmu on windows host (hardly
found documentation)?

Sorry if this is not the appropriate list. In this case please move or
delete.

Thanks for all the help
