20 Virtualization with Xen
For best performance, create each virtual disk from an entire disk or a partition.
For the next best performance, create an image file but do not create it as a sparse
image file. A virtual disk based on a sparse image file delivers the most disk-
space flexibility but slows installation and disk access speeds.
By default, a single, file-backed virtual disk is created as a sparse image file in
/var/lib/xen/images/vm_name where vm_name is the name of the
virtual machine. You can change this configuration to meet your specific require-
ments.

a randomly generated MAC address that you can change to fit your desired con-
figuration. The virtual network card will be attached to a default bridge configured
in the host. You can also create additional virtual network cards in the Network
Adapters page of vm-install.
NOTE: Using Arbitrary Bridge Names
If installing a fully virtualized guest and you are using a bridge name that
is different than the default names, explicitly specify the bridge by select-
ing the bridge name from the Source menu on the Virtual Network
Adapter page. Paravirtual guests by definition are aware they are running
on a virtualization platform and therefore, do not need to have the bridge
explicitly specified, thus leaving Source as Default will suffice.
file. In addition, if you are installing a SUSE Linux operating system, you can
install the operating system from a network installation source.
If you are installing a paravirtual machine's operating system from CD, you
should remove the virtual CD reader from the virtual machine after completing
the installation, because the virtual machine assumes that the original CD is still
in the CD reader, even if it is ejected. If it is ejected, the virtual machine cannot
access the CD (or any other newly inserted CD) and receives I/O errors.
