Zach Reizner b4af07af9c crosvm: add kernel command line builder 
The kernel command line is dynamically built up based on what devices
are added and what extra parameters are passed in my the user. The
module this CL adds ensures the kernel command line that is built is a
valid one.

Chrome OS KVM

This component, known as crosvm, runs untrusted operating systems along with virtualized devices. No actual hardware is emulated. This only runs VMs through the Linux's KVM interface. What makes crosvm unique is a focus on safety within the programming language and a sandbox around the virtual devices to protect the kernel from attack in case of an exploit in the devices.

Overview

The crosvm source code is organized into crates, each with their own unit tests. These crates are:

  • kvm-sys low-level (mostly) auto-generated structures and constants for using KVM
  • kvm unsafe, low-level wrapper code for using kvm-sys
  • crosvm the top-level binary front-end for using crosvm

Usage

Currently there is no front-end, so the best you can do is run cargo test in each crate.
