Hi，
Thank you for posting your query in community.
Per WS user guide https://docs.vmware.com/en/VMware-Workstation-Pro/15.0/workstation-pro-15-user-guide.pdf
Running Workstation on a Hyper-V Enabled Host is available in 15.5.5 version of Workstation Pro.
System Requirements
- Processor Requirements for Host System
- Intel Sandy Bridge or newer CPU
- AMD Bulldozer or newer CPU
- Supported Host Operating Systems
- Windows 10 20H1 build 19041.264 or newer
Nested VMs/PMCs/RTM and HLE/PKUare not supported so far.
Could you please try to change the Hyper-V status as follow:
How to change Hyper-V status
- By Windows Powershell tools to Enable/Disable Hyper-V
- Download Windows Powershell tools
dgreadiness_v3.6 is a tool that Microsoft published to enabled/disable Device Guard/Credential Guard
-- https://www.microsoft.com/en-us/download/details.aspx?id=53337
- Execute dgreadiness_v3.6 scripts with proper parameter by administrator user
Set-ExecutionPolicy Unrestricted if needed
If Execution-Policy is not already set to allow running script, then you should manually set it as below and then use the readiness script:
- Set-ExecutionPolicy Unrestricted
- DG_Readiness_Tool_v3.6.ps1 -Enable
To Enable DG/CG. If you have a custom SIPolicy.p7b then use the -Path parameter else the hardcoded default policy is used
Usage: DG_Readiness.ps1 -Enable OR DG_Readiness.ps1 -Enable -Path <full path to the SIPolicy.p7b>
- DG_Readiness_Tool_v3.6.ps1 -Disable
To Disable DG/CG. For more usage, you can refer to the readme.txt from the download bundle file.
- Reboot
How to verify your host is ready to run with/without Hyper-V?
Check Hyper-V & VBS Status & Device Guard status
By windows cmd line msinfo32.exe
