1. Overview
To make it possible to enhance the virtualization type support in DTC-Xen (eg: support for more virtualization types), we need:
- Make the sh scripts support more bootstrapping types
- Add support for fsck / start / stop / shutdown for the new virtualization types
- Add support for monitoring for the new virtualization types
2. Planned solutions
