ESX and vCenter Server Installation Guide

vSphere Client Software Requirements

Make sure that your operating system supports the vSphere Client.
The vSphere Client requires the Microsoft .NET 3.0 SP1 Framework. If your system does not have it installed,
the vSphere Client installer installs it.
For a list of supported operating systems, see the Compatibility Matrixes on the VMware vSphere documentation
Web site.

Support for 64-Bit Guest Operating Systems

ESX offers support for several 64-bit guest operating systems.
See the Guest Operating System Installation Guide for a complete list.
64-bit guest operating systems have specific hardware requirements:
For AMD Opteron-based systems, the processors must be Opteron Rev E and later.
n
For Intel Xeon-based systems, the processors must include support for Intel Virtualization Technology
n
(VT). Many servers that include CPUs with VT support might ship with VT disabled by default, so you
must enable VT 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 64-bit VMware support, you can download the CPU Identification
Utility at the VMware downloads page: http://www.vmware.com/download/shared_utilities.html.

Requirements for Creating Virtual Machines

To create a virtual machine, the ESX/ESXi host must be able to support a virtual process, a virtual chip set, and
a virtual BIOS.
Each ESX/ESXi machine has the requirements shown in
Table 2-6. Requirements for Creating Virtual Machines

Virtual processor
Virtual chip set
Virtual BIOS

Required Ports

vCenter Server requires certain ports to send and receive data.
The vCenter Server system must be able to send data to every managed host and receive data from every
vSphere Client. To enable migration and provisioning activities between managed hosts, the source and
destination hosts must be able to receive data from each other.

Requirements
One, two, or four processors per virtual machine
N If you create a two-processor virtual machine, your ESXi machine must have
OTE
at least two physical processors. For a four-processor virtual machine, your ESXi
machine must have at least four physical processors.
