August 2008

This document is intended for system administrators who wish to install Oracle VM Server. This document discusses downloading and installing Oracle VM Server. It contains:

- Preinstallation Tasks and Requirements

- Installing Oracle VM Server From a CDROM

- Installing Oracle VM Server From Other Sources

- Upgrading Oracle VM Server

- Documentation Accessibility

## 1 Preinstallation Tasks and Requirements

Before you start the Oracle VM Server installation, make sure your computer meets the minimum hardware and software requirements. This section contains:

- Hardware Requirements

- Software Requirements

- Network Requirements

- Getting the Software

### 1.1 Hardware Requirements

Oracle VM Server supports computers with x86 (i686) and x86_64 processors. This includes all Intel Pentium Pro or newer, and all AMD Athlon/Duron processors and newer. At least a Pentium 4 or Athlon CPU is recommended.

For hardware virtualized (unmodified) guest operating systems (for example, Microsoft Windows), a CPU with hardware virtualization support is required. This includes some Intel Pentium D, Core, Core2 and Xeon models, and some AMD Athlon and Opteron models. This feature may also need to be enabled in the BIOS. Please refer to your processor documentation for information on whether your processor supports hardware virtualization and how to enable it in the BIOS.

A dual core CPU or multiple CPUs are recommended to run multiple guests.

The minimum memory requirement is 1GB RAM, although it is recommended you have a computer with at least 2GB RAM. Guest memory requirements vary for each guest operating system. You should perform your own memory sizing for guest operating systems.

### 1.2 Software Requirements

There are no prerequisite software requirements. Oracle VM Server includes a small Linux-based management operating system. All previous operating systems and data are lost during the installation of Oracle VM Server.

Migration from any operating system, or previous virtualization environment, is not supported in this release.

### 1.3 Network Requirements

It is recommended that you install Oracle VM Server on a machine with a static IP address. If your machines uses DHCP you should configure your DHCP server to assign static DHCP addresses. This makes sure your host always receives the same IP address. The behavior of the Oracle VM Server host is undefined if used in an environment where your IP address may change due to DHCP lease expiry.

### 1.4 Getting the Software

If you do not already have the Oracle VM Server software, download the Oracle VM Server ISO file from:

`http://www.oracle.com/virtualization`

Burn the Oracle VM Server ISO file to a bootable CDROM.

You can install Oracle VM Server from a number of sources:

- Local CDROM

- Hard drive

- NFS server

- FTP server

- HTTP server

To install Oracle VM Server from a CDROM, see Section 2, "Installing Oracle VM Server From a CDROM".

To install Oracle VM Server from a hard drive, NFS server, FTP server, or HTTP server, see Section 3, "Installing Oracle VM Server From Other Sources".
