Boot Chromium OS on QEMU

I have successfully booted the Chromium OS on QEMU by running

 sudo qemu-system-x86_64 -kernel boot_images/vmlinuz -enable-kvm -m 2G -smp 4 -hda chromiumos_qemu_image.bin -vga virtio -append “init=/sbin/init root=/dev/sda3 earlyprintk=serial,keep console=ttyS0 cros_debug cros_efi”

and I could see the Chromum UI and enterrer setting menu on QEMU VGA console

I hope to change vga output to -vga std , I ran

 sudo qemu-system-x86_64 -kernel boot_images/vmlinuz -enable-kvm -m 2G -smp 4 -hda chromiumos_qemu_image.bin -vga std-append “init=/sbin/init root=/dev/sda3 earlyprintk=serial,keep console=ttyS0 cros_debug cros_efi”

but the QEMU VGA console only showed Chrome icon and did not move forward.

I added bochs-drm.ko to the kernel. So should I do other steps to fix this problem?
