running Xorg in VM (qemu)

["Enrico Weigelt, metux IT consult" <lkml%metux.net@localhost>]

Hi folks,

I'm struggling with getting Xorg running on Netbsd-10.1 inside an Qemu
VM (host is gnu/linux).

[ 13393.669] (II) LoadModule: "modesetting"
[ 13393.670] (II) Loading /usr/X11R7/lib/modules/drivers/modesetting_drv.so

qemu command line:
qemu-system-x86_64 -name netbsd-10.1-amd64 -smp 8 -m 8192 -hda
/home/nekrad/src/xorg/xorg-testing/vm/images/netbsd/netbsd-10.1-amd64-ci.qcow2
-enable-kvm -machine q35 -cpu max -k de_de -nic
user,model=virtio-net-pci,hostfwd=tcp::2023-:22 -bios
/usr/share/ovmf/OVMF.fd -vga std


What puzzles me: it doesn't seem to try any different driver than
modesetting (even though vesa and wsfb drivers are there)

Do I need some extra configuration here ?


thx
