Ubuntu 16.04: Build ChromiumOS

This article will describe building ChromiumOS and running ChromiumOS on KVM.

1 Build ChromiumOS

Please install repo and create ${HOME}/.repo_.gitconfig.json beforehand.

$ cat ~/
  "color.ui": [
  "user.name": [
  "user.email": [

The following command will create chromium_image.bin.

$ sudo apt install -y git-core gitk git-gui subversion curl
$ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
$ export PATH=${PWD}/depot_tools/:${PATH}
$ mkdir chromium
$ cd chromium
$ repo init -u https://chromium.googlesource.com/chromiumos/manifest.git
$ repo sync
$ export BOARD=amd64-generic
$ cros_sdk -- ./build_packages --board=${BOARD}
$ cros_sdk -- ./build_image --board=${BOARD} dev

2 Write ChromiumOS to USB

Run the following command after inserting USB. Running USB boot with this USB will run ChromiumOS.

$ cros_sdk -- cros flash --board=${BOARD} usb://

3 Run ChromiumOS on QEMU

You can run ChromiumOS on QEMU with this. But I cannot connect to internet.

4 Run ChromiumOS on KVM with virt-manager

You need the following settings.

  • Add src/build/images/${BOARD}/latest/chromiumos_image.bin to "IDE Disk" as raw image.
  • Set "Device model" of "Virtual Network Interface" to e1000.
  • Set "Video Device" to cirrus.
  • Mouse pointer needs "VNC server", "EvTouch USB Graphics Tablet" as input device and running virt-viewer (virt-manager's viewer does not display mouse pointer).

virt-viewer displays as following.
