Supported Guest Operating Systems

The VMware Guest Operating System Installation Guideincludes information on supported guest operating systems.

You can download this document at:

http://www.vmware.com/support/pubs/vi_pubs.html

ESX offers support for a number of 64-bit guest operatingsystems.

See the Guest Operating System Installation Guide for a

complete list.


12/34


Supported Guest Operating Systems

There are specific hardware requirements for 64-bit guestoperating system support.

For AMD Opteron based systems, the processors must be Opteron Rev

E and later.

For Intel Xeon based systems, the processors must include support for

Intel Virtualization Technology (VT).Many servers that include CPUs with VT support might ship with VT disabled

by default, and VT must be enabled manually.

If your CPUs support VT but you do not see this option in the BIOS, contact

your vendor to request a BIOS version that lets you enable VT support.

To determine whether your server has the necessary support, youcan use a CPU Compatibility Tool at

http://www.vmware.com/download/vi/drivers_tools.html.

Prerequisites for Installing ESX

Before you begin the installation procedure, ensure that youhave done the following:

Make sure that the server hardware clock is set toUTC. This setting is in the system BIOS.

Make sure the host has a supported NIC.

The ESX installer needs a live network connectionto properly detect certain network settings, such asthe machine name under DHCP.

IPv6 is not supported for ESX installation. You do not need

to be connected if you are doing a CD-ROM/DVD install.

Download the ESX installation ISO and burn theimage onto a DVD.

About ESX Partitions

ESX includes physical, virtual, required, and optional partitions.

In ESX 4.0, /boot and vmkcore are physical partitions. The /,swap, and all the optional partitions are stored on a virtual diskcalled esxconsole.vmdk. The virtual disk is stored in the/vmfs/volumes/ directory. The default size ofesxconsole.vmdk is 8GB.

ESX has the following physical partitions:/boot Contains the ESX software and its support files. The disk thatyou install /boot onto must be the disk the BIOS chooses to bootfrom.

vmkcore Required to store core dumps for troubleshooting.VMware does not support ESX host configurations without a

vmkcore partition.

/vmfs Required to store your virtual machines. The/vmfs/volumes/ partition contains the esxconsole.vmdk,swap, and / - root partitions.


16/34


About ESX Partitions

The ESX installation includes separate installable components:ESX boot disk Requires 360MB of free space. The /boot and

vmkcore partitions are included on the ESX boot disk.

/vmfs/volumes Requires at least 8GB of free space and includes

the service console (VMDK disk) plus space for your other virtual

machines.You can install the ESX boot disk and /vmfs/volumes on a single

device or on two separate devices. If you install them on a single

device, the device must have at least 10.5GB of free space.


17/34


Installing ESX

The following methods are available for installing VMware ESXsoftware:

Graphical interface This is the recommended installation method.

Text mode Use this method if your video controller, keyboard, or

mouse does not function properly using the graphical installer.

Scripted An efficient way to deploy multiple hosts.


18/34


Installing VMware ESX 4.0

Installed ComponentsThe VMware ESX 4.0 installation includes the following

components:

VMware ESX 4.0 Software to manage and serve virtual

machines.

VMware vSphere Client - Software to allow access to the ESX

host.

VMware vSphere Web Access Software to allow a Web

browser access to the ESX host.


19/34


Installation on SATA Drives

When installing ESX on SATA drives, consider the followingsituations:

Ensure that your SATA drives are connected through supported

SAS controllers or supported on-board SATA controllers.

Do not use SATA disks to create VMFS datastores shared

across multiple ESX hosts.


20/34


To install ESX

Download the ISO file for ESX 4.0 from the VMware Web Site

Burn the iso file onto DVD media.

Insert the DVD into the DVD drive of a supported server

platform.

Power on the machine with the VMware ESX DVD in the

CD/DVD drive.

In the BIOS, set the server to boot from the DVD.

The ESX begins its boot process until the mode selection page appears.


21/34


Post install Considerations

Evaluation Period Countdown

The ESX 60-day evaluation period begins to count down immediately

after the first time you power on the ESX machine.

Locate the Installation Log

After you install and reboot, log in to the service console to read the

installation log at /var/log/weasel.log

Download the vSphere Client

The vSphere Client is a Windows program that you can use to

configure the ESX host and to operate its virtual machines.You can download vSphere Client from any ESX host.

You must obtain the URL of an ESX host. This is the IP address or machinename.

To download the vSphere Client

From a Windows machine, open a Web browser.Enter the URL for the ESX host.For example, enterhttp://testserver.vmware.com/The VMware ESX welcome page appears.

Click the Download the VI Client link under Getting Started.A security warning dialog box appears.

Click Yes.

Install the client.


24/34


Remote and Scripted Installations

After you install ESX on a system, you can quickly deploy more

ESX hosts by using scripted installations.

Scripted installations provide an efficient way to deploy multiple

hosts.

The ESX scripted installation method is similar to Red Hats

kickstart installation method.

The script is a kickstart configuration file, which consists of the

choices you want to make during the installation of ESX.

The ESX scripted installation is incompatible with Red Hats

kickstart installation method or files.


25/34


Remote and Scripted Installations

Scripted installations include the following steps:Create a kickstart file using the commands shown in the ESX

and vCenter Server Installation Guide

Edit the kickstart configuration file as needed to change settings

that are unique for each server.

Run the scripted install locally from the CD-ROM drive of the

new system or remotely over a network using installation files

that are hosted on a remote ESX.

Run a Scripted Installation from the Kickstart File

Type one of the following commands:

esx ks=cdrom:/ks.cfg- Kickstart file is located on the CDROM drive attached to the machine.

esx ks=file:///ks.cfg

- Kickstart file is at which resides inside the initial RAM disk image.

esx ks=http:////ks.cfg

- Kickstart file is located at the given URL.

esx ks=nfs:////ks.cfg

- Kickstart file is located at on a given server.

esx ks=usb

Kickstart file is in the root directory of a USB flash drive

esx ks=UUID:://ks.cfg

Kickstart file is located on the partition with the given UUID and path.

Press Enter to start the scripted installation.

ESX PartitioningRequired Partitions

An ESX local boot volume requires three specific partitions for operation.In addition, a local or remote VMFS partition is required to store your virtualmachines, and a vmkcore partition is required to provide core dumps for technicalsupport.

For /var/log, VMware recommends a separate partition to preventunexpected disk space constraints from compromising ESX operations.Increase this partition by 512MB if you perform a remote or scripted

installation from the ESX machine.In ESX 4.0, the /boot, vmkcore, and /vmfs are physical partitions.

The /, swap, and all the optional partitions are stored on a virtual disk

You cannot define the sizes of the /boot, vmkcore, and /vmfs partitionswhen you use the GUI or text installation methods

You can define these partition sizes when you do a scripted installationAfter installation, the esxconsole-.vmdk file is created on the /vmfspartition. The /, swap, and the optional partitions are stored in the esxconsole-.vmdk file.
