VMware GSX Server 2.5.2Features | Documentation | Knowledge Base | Discussion Forums This section offers advice for configuring a Linux guest operating system for better performance inside a GSX Server virtual machine. Note: This document pertains to the guest operating system that is running inside a GSX Server virtual machine. It does not describe actions that should be taken on Linux running on the host. Make certain you have selected the correct guest operating system in the Configuration Editor — Settings > Configuration Editor > Options (on Windows hosts) or Settings > Configuration Editor > Misc (on Linux hosts). Make certain VMware Tools is installed. VMware Tools provides an optimized SVGA driver and sets up the VMware Tools service to run automatically when the system starts. Among other things, the VMware Tools service allows you to synchronize the virtual machine's clock with the host computer's clock, which can improve performance for some functions. You can install VMware Tools by choosing Settings > VMware Tools Install. Using the Devices menu, disconnect your CD-ROM drive if you do not need to use it. If you are using a Linux host, also disconnect /dev/rtc. Disconnecting these devices reduces CPU usage. Note: The time synchronization feature in VMware Tools does not rely on /dev/rtc. When you are installing your Linux guest operating system, use the text-mode installer instead of the graphical installer if you have a choice. This makes the installation process faster. If you do use a graphical installer and if you are using a Linux host computer, try to run the virtual machine in a local console in full screen mode during the installation. Run your virtual machine in full screen mode. Click the Full Screen button on the local console toolbar. You can use full screen mode only when the virtual machine is running in a local console.
