VMware Tools Service
The VMware Tools service starts when the guest operating system starts. The service passes information
between host and guest operating systems.
This program, which runs in the background, is called vmtoolsd.exe in Windows guest operating systems,
vmware-tools-daemon in Mac OS X guest operating systems, and vmtoolsd in Linux, FreeBSD, and Solaris
guest operating systems. The VMware Tools service performs the following tasks:
n
Passes messages from the host to the guest operating system.
n
Provides support for customization of guest operating systems as a part of the vCenter Server and other
VMware products.
n
Provides support for guest operating system-bound calls created with the VMware VIX API, except in
Mac OS X guest operating systems.
n
Runs scripts that help automate guest operating system operations. The scripts run when the power
state of the virtual machine changes.
n
Synchronizes the time in the guest operating system with the time on the host.
n
In Windows guest operating systems, allows the pointer to move freely between the guest and the
vSphere Web Client.
On Linux guest operating systems that run Xorg 1.8 and later, this functionality is available as a
standard feature.
n
In Windows and Mac OS X guest operating systems, fits the screen display resolution of the guest to the
screen resolution of the vSphere Web Client, if running in full screen mode. If running in windowed
mode, fits the screen resolution of the guest to the size of the window on the client or host.
n
In Windows and Linux guest operating systems, helps create the quiesced snapshots used by certain
backup applications.
n
In Windows, Linux, Solaris, and FreeBSD guest operating systems, runs custom power-on script in the
virtual machine when you shut down or restart the guest operating system.
n
Is one of the processes that sends a heartbeat to the VMware product to indicate that the guest
operating system is running. When the virtual machine runs under ESXi or vCenter Server, a gauge for
this heartbeat appears in the management interface.
n
Provides support for guest operating on Windows and Linux created using the VMware VIX API,
except in Mac OS X guest operating systems. For information VIX API, see the vSphere API Reference
documentation.
VMware Tools Device Drivers
Device drivers optimize mouse operations and improve sound, graphics, and networking performance. If
you do a custom VMware Tools installation or reinstallation, you can choose which drivers to install.
Which drivers are installed when you install VMware Tools also depends on the guest operating system and
the VMware product. For detailed information about the features or functionality that these drivers enable,
including configuration requirements, best practices, and performance, see the documentation for your
VMware product. The following device drivers can be included with VMware Tools.
SVGA driver
This virtual driver enables 32-bit displays, high display resolution, and
significantly faster graphics performance. When you install VMware Tools, a
virtual SVGA driver replaces the default VGA driver, which allows for only
640 X 480 resolution and 16-color graphics.
