VMware GSX Server Administration Guide
Remote Disk Access
Whenever possible, do not use disks that are on remote machines and accessed over
the network unless you have a very fast network. If you must run disks remotely,
choose VM > Settings > Options, select General and set the Working directory to a
directory on your local hard disk. Then take a snapshot. After you take the snapshot,
changes you make are stored locally in the working directory.
Snapshots
If you do not need to use snapshots, it is best to run your virtual machine without a
snapshot. This provides best performance. To be sure a virtual machine has no
snapshot, choose Snapshot > Remove Snapshot.
Issues Installing or Running Applications in a Guest Operating System
You may notice that whenever you try to install or start a particular program in a
virtual machine, the program seems to hang, crash or complain that it is running
under a debugger. VMware has seen this problem with a few programs, including the
installer for the Japanese version of Trend Micro Virus Buster, the FoxPro database, the
NetWare client in Windows 98, Mathcad, The Sims and Civilization III.
You can work around this problem by using a special setting called disabling
acceleration. Frequently, the problem occurs only during installation or early in the
program's execution; in that case you should turn acceleration back on after getting
past the problem. Follow these steps:
1. Power on the virtual machine.
2. Before running or installing the program that was encountering problems,
disable acceleration.
Choose VM > Settings > Advanced and check Disable acceleration.
3. Click OK to save the change and close the virtual machine settings editor.
4. Start the program or run the installer.
5. After you pass the point where the program was encountering problems, return
to the virtual machine settings editor and remove the check beside Disable
acceleration. You may be able to run the program with acceleration after it is
started or installed.
Note: Disabling acceleration can help you get past the execution problem, but
it causes the virtual machine to run slowly. If the problem occurs only at startup
or during installation, you can improve performance by resuming accelerated
operation after the program that was encountering problems is running or is
installed.
