This chapter assumes that VMware Tools have been successfully installed and configured on one or more VMware Server 2.0 guest operating systems. If this is not yet the case, a review of the [[Understanding and Installing VMware Tools|previous]] chapter is recommended before proceeding with this chapter.
Assuming VMware Tools are installed and running, this chapter will cover the subject of using these tools to gain the maximum functionality from VMware Server 2.0 guest operating systems. Topics covered in this chapter include the VMware Tools control panel, power state change scripts and the use of VMware Tools from the command-line.
== Accessing The VMware Tools Control Panel ==
The default configuration for VMware Tools on Windows should have placed a VMware Tools icon in the Windows notification area in the bottom right hand corner of the Windows task bar (where the date and time are typically displayed) and also as an icon in the Windows Control Panel (accessed via ''Start->Control Panel'').
The following figure illustrates a taskbar from a Windows server Server 2008 desktop containing the VMware Tools icon (the second icon from the left in the notification area):
== Configuring Host and Guest Time Synchronization ==
The VMware Tools control panel consists of a number of tabs which serve to display different groups of configuration options. The first tab, labeled ''Options'' , contains a number of miscellaneous configuration settings, perhaps the most significant of which relates to time synchronization between host and guest systems.
The ''Time synchronization between the virtual machine and the host operating system'' setting controls whether VMware Tools checks at one minute intervals to ensure the guest operating system's time has not fallen behind that of the host system. Deselecting this option prevents VMware Tools from performing this check while the guest system is up and running. Strangely, however, it does not prevent the synchronization check from being performed when the virtual machine is started, resumed, restored from a snapshot, or when the size of virtual disk is reduced using VMware Tools.
When selected, the ''Show VMware Tools in the taskbar'' option displays the VMware Tools icon within the notification area of the Windows taskbar. Double clicking on this icon will invoke the VMware Tools control panel.
The ''Notify if update is available'' option causes the taskbar icon to be displayed with a yellow warning symbol to when an update to VMware Tools is available for installation from the host system. In the event that an update is available, the ''Update Tools'' button will be enabled and may be pressed to initiate the upgrade process.
== Device Configuration Options ==
The device tab of the VMware Tools control panel allows certain removal removable devices to be attached to and detached from the virtual machine from within the guest operating system. In the event that a device is not listed on this page of the control panel it can still be attached and detached using the ''Devices'' menu of the VMware Remote Console.
== VMware Tools Script Configuration ==
The VMware Tools control panel scripts ''Scripts'' tab displays a number of configuration options relating to scripts. Scripts perform tasks when the virtual machine in which the guest operating system is running is powered on, powered off, suspended or resumed. Default scripts are installed and configured to run when VMware Tools is installed on the guest. This page of the control panel, allows the default scripts to be enabled or disabled for each power state, or custom scripts to be specified. In addition, any existing script can be run by selecting the power state from the drop down menu and clicking on the ''Run Now'' button.
The VMware Tools scripts are covered in more detail in the [[Working with VMware Tools Scripts and Power States]] chapter.
The shrink tab of the VMware Tools control panel allows virtual disks associated with the virtual machine to be reduced in size by reclaiming unused areas on the disk. In the first instance, free space on the disk is reclaimed within the guest operating system. Subsequently, the virtual disk image on the host file system is then reduced in size by the VMware Server software.
In order to be able to perform a shrink operation the virtual disk must not be have been created as a ''pre-allocatedgrowable'' disk and there must be no current snapshots of the virtual machine. If the virtual disk is an ''independent'' disk it must be in ''persistent mode''. In the case of Linux guest operating systems, the operation must be performed as superuser. For further information on shrinking virtual disks in VMware Server 2.0and converting pre-allocated virtual disks to growable disks, refer to the chapter entitled [[Managing VMware Server 2.0 Virtual Disks]].
