- A functional Linux system with virtualization is multi-layered and is driven by the privileged Xen kernel component. Xen can host multiple guest operating systems. Each guest operating system runs in its own domain. Xen schedules virtual CPUs within the virtual machines to make the best use of the available physical CPUs. Each guest operating systems handles its own applications. These guest operating systems schedule each application accordingly.

- You can deploy Xen in one of two choices: <a class="firstterm" href="#glos-Virtualization_Guide-Full_virtualization"><em class="firstterm">full virtualization</em></a> or <a class="firstterm" href="#glos-Virtualization_Guide-Para_virtualization"><em class="firstterm">para-virtualization</em></a>. Full virtualization provides total abstraction of the underlying physical system and creates a new virtual system in which the guest operating systems can run. No modifications are needed in the guest OS or application (the guest OS or application is not aware of the virtualized environment and runs normally). Para-virtualization requires user modification of the guest operating systems that run on the virtual machines (these guest operating systems are aware that they are running on a virtual machine) and provide near-native performance. You can deploy both para-virtualization and full virtualization across your virtualization infrastructure.

- The first domain, known as <span class="application"><strong>domain0</strong></span> (dom0), is automatically created when you boot the system. Domain0 is the privileged guest and it possesses management capabilities which can create new domains and manage their virtual devices. Domain0 handles the physical hardware, such as network cards and hard disk controllers. Domain0 also handles administrative tasks such as suspending, resuming, or migrating guest domains to other virtual machines.

For para-virtualized guests, you can set both the initial memory and the maximum size of the virtual machine. You can add (or remove) physical memory to the virtual machine at runtime without exceeding the maximum size you specify. This process is called ballooning.

The domain-id is a unique, non-persistent number that gets assigned to an active domain can identify and control that guest. The UUID is a persistent, unique identifier that is controlled from the guest's configuration file and ensures that the guest is identified over time by system management tools. It is visible to the guest when it runs. A new UUID is automatically assigned to each guest by the system tools when the guest first installs.
