Supported Guest Operating Systems
The VMware Guest Operating System Installation Guide includes 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 operating systems.
See the Guest Operating System Installation Guide for a complete list.
VI4 - Mod 1-2 - Slide 14
Supported Guest Operating Systems
There are specific hardware requirements for 64-bit guest operating 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, you can use a CPU Compatibility Tool at http://www.vmware.com/download/vi/drivers_tools.html.
VI4 - Mod 1-2 - Slide 15
Virtual Machine Requirements
Virtual processor
One, two, four or eight processors per virtual machine
NOTE If you create a two-processor virtual machine, your ESX machine must have at least two physical processors. For a four-processor virtual machine, your ESX machine must have at least four physical processors.

VI4 - Mod 1-2 - Slide 16
Prerequisites for Installing ESX
Before you begin the installation procedure, ensure that you have done the following:
Make sure that the server hardware clock is set to UTC. This setting is in the system BIOS.
Make sure the host has a supported NIC.
The ESX installer needs a live network connection to properly detect certain network settings, such as the 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 the image onto a DVD.
VI4 - Mod 1-2 - Slide 17
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 disk called esxconsole.vmdk. The virtual disk is stored in the /vmfs/volumes/<UUID> directory. The default size of esxconsole.vmdk is 8GB.
ESX has the following physical partitions:
/boot – Contains the ESX software and its support files. The disk that you install /boot onto must be the disk the BIOS chooses to boot from.
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/<UUID> partition contains the esxconsole.vmdk, swap, and / - root partitions.
VI4 - Mod 1-2 - Slide 18
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.
VI4 - Mod 1-2 - Slide 19
Installing ESX
The following methods are available for installing VMware ESX software:
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.
VI4 - Mod 1-2 - Slide 23
Installing VMware ESX 4.0
Installed Components
The 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.
VI4 - Mod 1-2 - Slide 24
Installation on SATA Drives
When installing ESX on SATA drives, consider the following situations:
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.
VI4 - Mod 1-2 - Slide 26
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.
VI4 - Mod 1-2 - Slide 27
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.

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 machine name.
To download the vSphere Client
From a Windows machine, open a Web browser.
Enter the URL for the ESX host.For example, enter http://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.
VI4 - Mod 1-2 - Slide 36
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 Hat’s 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 Hat’s kickstart installation method or files.
VI4 - Mod 1-2 - Slide 37
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 FileType 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://<path>/ks.cfg- Kickstart file is at <path> which resides inside the initial RAM disk image.
esx ks=http://<server>/<path>/ks.cfg- Kickstart file is located at the given URL.
esx ks=nfs://<server>/<path>/ks.cfg- Kickstart file is located at <path> on a given server.
esx ks=usbKickstart file is in the root directory of a USB flash drive
esx ks=UUID:<disk-uuid>:/<path>/ks.cfg Kickstart file is located on the partition with the given UUID and path.
Press Enter to start the scripted installation.
VI4 - Mod 1-2 - Slide 49
ESX Partitioning
Required PartitionsAn ESX local boot volume requires three specific partitions for operation.
In addition, a local or remote VMFS partition is required to store your virtual machines, and a vmkcore partition is required to provide core dumps for technical support.
For /var/log, VMware recommends a separate partition to prevent unexpected 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 partitions when you use the GUI or text installation methods
You can define these partition sizes when you do a scripted installationAfter installation, the esxconsole-<UUID>.vmdk file is created on the /vmfs partition. The /, swap, and the optional partitions are stored in the esxconsole-<UUID>.vmdk file.
