The vOS is a minimal operating system for Docker and KVM and it is stand for Virtualized OS.

cdx-build

Integration setup scripts for the Angstrom and Buildroot br2-external feature.

CDX Build Environment

Build system based on buildroot for build vOS and cdxvirt platform. The vOS is a minimal operating system for cloud, mainly for run containers and virtual machines. It is stand for Virtualized OS.

Example

This following is example of building and installing a linux system from scratch for the default qemu config.

• git clone https://github.com/xlcwu/cdx-build.git

• cd cdx-build

• . envsetup

• cdx_setup

• cdx-build qemu_x86_64_defconfig && cdx-build

• cdx-build printvars

• cdx-build list-defconfigs

Motivation

This build template is designed to be used for production build systems (used to build product software), and thus has the following goals:

1. simplicity: uses well understood things like bash and git submodules.
2. robustness: Git submodules are a robust solution for production environments, and error handling good. Git submodules are also very good at making sure you are building exactly what was checked in, because it locks every submodule down to a specific version, which is generally what you want for a production build system, where the build must be absolutely repeatable.
3. generate a modern Linux root filesystem.
