VMware GSX Server Administration Guide
adjusting the settings in the virtual machine settings editor (choose VM > Settings >
Memory ).
If you plan to run one virtual machine at a time most of the time, a good starting point
is to give the virtual machine half the memory available on the host.
Adjusting the reserved memory settings may also help. Choose Host > Settings >
Memory .
For additional information, see Understanding Memory Usage on page 194 .
Debugging Mode
You can configure each virtual machine to run in one of two modes — normal mode
and a mode that provides extra debugging information. The debugging mode is
slower than normal mode.
For normal use, make sure the virtual machine is not running in debugging mode.
Choose
VM > Settings > Options and select Advanced . Under Settings , make sure
the Run with debugging information check box is cleared.
CD-ROM Drive Polling
Some operating systems — including Windows NT and Windows 98 — poll the CD-
ROM drive every second or so to see whether a disc is present. (Doing this allows
them to run autorun programs.) This polling can cause GSX Server to connect to the
host CD-ROM drive, which can make the CD-ROM drive spin up while the virtual
machine appears to pause.
If you have a CD-ROM drive that takes especially long to spin up, there are two ways
you can eliminate these pauses.
• You can disable the polling inside your guest operating system. The method
varies by operating system. For recent Microsoft Windows operating systems,
the easiest way is to use TweakUI from the PowerToys utilities.
For information on finding TweakUI and installing it in your guest operating
system, go to
www.microsoft.com and search for TweakUI. Specific instructions
depend on your operating system.
• Another approach is to configure your virtual CD-ROM drive to be disconnected
when the virtual machine starts. The drive appears in the virtual machine, but it
always appears to contain no disc (and GSX Server does not connect to your
host CD-ROM drive).
To make this change, go to VM > Settings . Select the DVD/CD-ROM item in the
Device list. Then clear the Connect at Power On check box.
