Bug Description

The bochs-drm module is not enabled in the build config of the linux-kvm kernel.

Therefore, there is no display output when running in QEMU with -vga std.
The image I used is focal-server-cloudimg-amd64-disk-kvm.img from cloud-images.ubuntu.com.

Steps to reproduce:
1. curl -LO https://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
2. qemu-system-x86_64 -enable-kvm -hda focal-server-cloudimg-amd64-disk-kvm.img -vga std <additional ram & cpu options...>
3. Observe the screen stay on the boot message

The missing Kconfig is CONFIG_DRM_BOCHS=y

Ubuntu release: Ubuntu 20.04.1 LTS
linux-kvm version: 5.4.0.1026.24 (amd64)
