I tried that first and it was horribly slow. That's why I try hardware acceleration now.

Do you _know_ it doesn't work? If yes, why?

If you want an aarch guest on x86, then drop the gl option from
runqemu. This will fall back to software rendering.

Sorry, but I need an Aarch64 guest.

Ok, using a newer qemu I now encounter the following problem:

What is this bochs-drm_dri.so and does Yocto / the Mesa in Yocto provide it?

This configuration is not tested. If you want accelerated gl, build
for the qemux86-64 target.

Greetings,

I tried to run an Aarch64 Yocto with qemu on amd 64 Host. For that purpose, I built core-image-weston from Hardknott following the manual

https://www.mail-archive.com/yocto@lists.yoctoproject.org/msg07306.html

I then try to run

runqemu sdl gl

But it always aborts with

runqemu - ERROR - Failed to run qemu: qemu-system-aarch64: Virtio VGA not available.

What can I do?

Regards
