Products such as VMware Server and VMware Workstation are hypervisors that sit on top of a guest operating system, so some of the server resources are taken up by the host operating system. ESX Server is the enterprise level hypervisor from VMware, which installs on the "bare-metal", making it significantly more efficient. Once installed, you are able to create virtual machines, each running as a complete system, with processors, memory, networking, storage and BIOS. This article describes the "bare-metal" installation and basic usage of VMware ESX Server 3.5 Update 2. - Download Software - VMware ESX Server Installation - VMware Infrastructure Client Installation - Virtual Machine Setup - Guest Operating System Installation - VMware Tools Installation Download the following software. - VMware ESX Server Start the VMware ESX Server installation by booting from the VMware ESX Server CD.

Start the VMware Toolbox using the "vmware-toolbox" command. Select the time synchronization options, then close the dialog.

Reboot the server and the virtual machine installation is complete. You can now start using your virtual machine just like any other server. For more information see: - VMware Hope this helps. Regards Tim...
