VMCH-67-000023
(in versions v1 r3 through v1 r1)
Title
3D features on the virtual machine must be disabled when not required. (Cat III impact)
Discussion
It is recommended that 3D acceleration be disabled on virtual machines that do not require 3D functionality, (e.g. most server workloads or desktops not using 3D applications).
Check Content
From the vSphere Web Client select the Virtual Machine, right click and go to Edit Settings >> VM Options Tab >> Advanced >> Configuration Parameters >> Edit Configuration. Find the "mks.enable3d" value and verify it is set to "false". or From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the following command: Get-VM "VM Name" | Get-AdvancedSetting -Name mks.enable3d If the virtual machine advanced setting "mks.enable3d" does not exist or is not set to "false", this is a finding. If a virtual machine requires 3D features, this is not a finding.
Fix Text
From the vSphere Client select the Virtual Machine, right click and go to Edit Settings >> VM Options Tab >> Advanced >> Configuration Parameters >> Edit Configuration. Find the "mks.enable3d" value and set it to "false". Note: The VM must be powered off to modify the advanced settings through the vSphere Web Client. It is recommended to configure these settings with PowerCLI as this can be done while the VM is powered on. In this case, the modified settings will not take effect until a cold boot of the VM. or From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the following command: If the setting does not exist, run: Get-VM "VM Name" | New-AdvancedSetting -Name mks.enable3d -Value false If the setting exists, run: Get-VM "VM Name" | Get-AdvancedSetting -Name mks.enable3d | Set-AdvancedSetting -Value false
