Check: VMCH-70-000023
VMware vSphere 7.0 Virtual Machine STIG:
VMCH-70-000023
(in versions v1 r3 through v1 r2)
Title
All 3D features on the virtual machine (VM) must be disabled when not required. (Cat III impact)
Discussion
For performance reasons, 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
For each virtual machine do the following: From the vSphere Client, right-click the virtual machine and go to Edit Settings. Expand the "Video card" and verify the "Enable 3D Support" checkbox is unchecked. 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" exists and is not set to "false", this is a finding. If the virtual machine advanced setting "mks.enable3d" does not exist, this is not a finding.
Fix Text
For each virtual machine do the following: From the vSphere Client, right-click the virtual machine and go to "Edit Settings". Expand the "Video card" and uncheck the "Enable 3D Support" checkbox. Click "OK". or From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the provided commands as noted below. 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 Note: The VM must be powered off to configure the advanced settings through the vSphere Client. Therefore, it is recommended to configure these settings with PowerCLI as this can be done while the VM is powered on. Settings do not take effect via either method until the virtual machine is cold started, not rebooted.
