How to Install Chrome OS Flex on Your Computer

Do you want to install Chrome OS on your computer? Chromium OS (or Chrome OS for short) is a lightweight, open-source operating system developed by Google for their line of personal computers called Chromebooks. Chrome OS is a cloud-based operating system that doesn't require as much hardware as other computer operating systems. Installing Chrome OS on an old laptop or PC is a good way to breathe new life into it. Luckily, Google has released Chrome OS Flex, which is an official distribution of Chrome OS that can be installed on Windows PCs, Macs, and Linux computers. The only difference between Chrome OS on Chromebooks and Chrome OS Flex is it does not have the Google Play Store and you cannot install Android apps on it. This How.com.vn article teaches you how to install Chrome OS Flex on your computer.

Question
How do I install it in VirtualBox or QEMU?
Community Answer
You can't install Chromium OS in VirtualBox because of graphics issues. With QEMU/KVM, AFAIK you have to build Chromium OS from source, though it will work fine if you do. You can also download VM images from Cloudready, which will work in VMWare player.
