For best performance, create each virtual disk from an entire disk or a partition. For

the next best performance, create an image le but do not create it as a sparse image

le. A virtual disk based on a sparse image le delivers the most disk-space exibil-

ity but slows installation and disk access speeds.

By default, a single, le-backed virtual disk is created as a sparse image le in

/var/lib/xen/images/vm_name where vm_name is the name of the virtual

machine. You can change this conguration to meet your specic requirements.

If you want to install from DVD or CD-Rom, add the drive to the list of available

hard disks. To learn about device names of the available optical drives, run hwinfo

--cdrom and search for the line starting with Device File:. Add this device

le to the available hard disks of the VM Guest.

By default, a single virtual network card is created for the virtual machine. It has a

randomly generated MAC address that you can change to t your desired congura-

tion. The virtual network card will be attached to a default bridge congured 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 selecting

the bridge name from the Source menu on the Virtual Network Adapter

page. Paravirtual guests by denition are aware they are running on a virtu-

alization platform and therefore, do not need to have the bridge explicitly

specied, thus leaving Source as Default will sufce.

The operating system can be installed from a CD/DVD device or an ISO image le.

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 installa-

tion, 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.
