Reduce Memory Overhead for Virtual Machines with 3D Graphics Option
Virtual machines with the 3D graphics option enabled can have higher memory consumption than other
virtual machines. You can reduce the memory overhead by editing the configuration file (.vmx file) of your
virtual machines and disabling certain memory-related settings. Reducing the memory overhead of virtual
machines can help you increase the number of virtual machines per host.
Prerequisites
Verify that your virtual machines are using hardware version 10 or later.
Procedure
1 Shut down the virtual machine on which the 3D graphics option is enabled.
2 Disable the Accelerate 3D Graphics option.
3 Upgrade your ESXi host to use the features available in hardware version 10 or later.
4 Set the maximum size of your display to the size you need.
5 Locate the configuration file (.vmx) of your virtual machine.
6 Open the virtual machine configuration file in a text editor and add the line, svga.vgaOnly=TRUE.
This option removes all graphics and SVGA functionality from your SVGA device, but does not
remove the settings that allow BIOS to enter VGA mode.
7 Save the changes and exit the text editor.
8 Power on your virtual machine and check the display console.
9 Verify the memory reservation settings in the vmware.log file.
Add an NVIDIA GRID vGPU to a Virtual Machine
If an ESXi host has an NVIDIA GRID GPU graphics device, you can configure a virtual machine to use
the NVIDIA GRID virtual GPU (vGPU) technology.
NVIDIA GRID GPU graphics devices are designed to optimize complex graphics operations and enable
them to run at high performance without overloading the CPU. NVIDIA GRID vGPU provides unparalleled
graphics performance, cost-effectiveness and scalability by sharing a single physical GPU among multiple
virtual machines as separate vGPU-enabled passthrough devices.
Prerequisites
n
Verify that an NVIDIA GRID GPU graphics device with an appropriate driver is installed on the host.
See the vSphere Upgrade documentation.
n
Verify that the virtual machine is compatible with ESXi 6.0 and later.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
