System Architecture
Virtual networking interfaces runs on the guest. Other interfaces can run on the guest like virtual ethernet internet cards (VNICs). These network interfaces are configured with a persistent virtual media access control (MAC) address. The default installation of a new guest installs the VNIC with a MAC address selected at random from a reserved pool of over 16 million addresses, so it is unlikely that any two guests will receive the same MAC address. Complex sites with a large number of guests can allocate MAC addresses manually to ensure that they remain unique on the network.
Each guest has a virtual text console that connects to the host. You can redirect guest logins and console output to the text console.
You can configure any guest to use a virtual graphical console that corresponds to the normal video console on the physical host. You can do this for full virtual and paravirtual guests. It employs the features of the standard graphic adapter like boot messaging, graphical booting, multiple virtual terminals, and can launch the x window system. You can also use the graphical keyboard to configure the virtual keyboard and mouse.
Guests can be identified in any of three identities: domain name (domain-name), identity (domain-id), or UUID. The domain-name is a text string that corresponds to a guest configuration file. The domain-name is used to launch the guests, and when the guest runs the same name is used to identify and control it. The domain-id is a unique, non-persistent number that gets assigned to an active domain and is used to identify and control it. 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.
