Understanding and Installing VMware Tools
A key area where VMware Server differs from many other virtualization solutions is the ability to install tools (known as VMware Tools) onto the guest operating system. VMware Tools are available for Windows, Linux, FreeBSD and Netware guest operating systems and are designed to both improve the functionality of the guest within the virtual machine environment, and to enhance interaction between the guest and the host.
An Overview of VMware Tools
The VMware Tools package comprises four categories of utilities, each of which performs one or more specific purposes:
VMware Device Drivers
VMware Server presents the physical host hardware to the guest operating system as virtual devices. For example, whilst the host computer may have an Intel Gigabit Ethernet Adapter installed, the virtual network adapters presented to a 32-bit guest operating system appear as AMD PCnet‐PCI II devices. In order to ensure optimal performance of the guest in relation to these virtual devices, VMware Tools includes device drivers for each device category. These device drivers are so important, in fact, that without VMware Tools installed, the guest operating system may be unable to establish a network connection (currently the case with Windows Server 2008) because it lacks a built-in driver for the AMD network adapter, or drive the VMware Remote Console at anything above a rudimentary screen resolution. Installation of VMware Tools avoids these and other driver compatibility problems.
