Creating a Virtual Server - domU There are 3 options of what to run DomU on: 1. File Based Image 2. LVM Based 3. Physical Partition 1. A file based image is the quickest to setup, however has poor/terrible IO performance. The virtual server is limited to the initial size of the image created also. The file based Image can however be easily mounted in a rescue system, and easily backed-up. 2. LVM for domU is the industry standard. After the initial setup of LVM, as described here, it is a dream to manage. LVM partitions can be resized afterwards!!! Due to this "resizing" capability and flexibility, its use for Xen Virtual Servers is ideal. They also have much better IO performance than file-based. I dont know about mounting these partitions however in a rescue system. Something to try out... -). 3. Physical Partitions have the best IO, but are difficult to alter and inflexible.
