I applied the solution ways in the link but I couldn't succeed again. Who has a different opinion?
I made Hyper-V disable, again I encountered the same error.
Your host does not meet minimum requirements to run VMware Workstation with Hyper-V or Device/Credential Guard enabled. Refer to VMware KB article 76918 at https://kb.vmware.com/kb/76918 for more details.
If and only if you are on 15.5.5 of Vmware workstation pro and your host is on Windows 10 version 2004, you need to go into the vm settings try under the hardware >> processors setting the virtualization (Intel or AMD) and the virtualization counters if your guest is any version of Windows.
In addition under the options tab >> advanced, make sure UEFI and secure boot are both checked for Windows 10 guests. For windows 7 guest make sure the BIOS instead of UEFI is selected. Prior versions may also need that BIOS setting also enabled.
I have not yet tried either "Credential guard" or "Device guard" active on the host OS. Please be aware to this point, I have seen nothing about this. I have given you the settings that work in my situation where the Host OS is Windows 10 version 2004 and the guests are Windows 10 version 1909 and Windows 7 service pack 1.
I hope this helps.
I forgot to note that I do have hyper-v installed on the host!
Thank you for posting your query in community.
Running Workstation on a Hyper-V Enabled Host is available in 15.5.5 version of Workstation Pro.
Nested VMs/PMCs/RTM and HLE/PKU are not supported so far.
Could you please try to change the Hyper-V status as follow:
How to change Hyper-V status
dgreadiness_v3.6 is a tool that Microsoft published to enabled/disable Device Guard/Credential Guard
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:
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>
To Disable DG/CG. For more usage, you can refer to the readme.txt from the download bundle file.
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
It is happen for vmware 14. as well. so i try the vmware 15, same result. after i updated windows 10 restart. need some quick bug fixes. I suspect is the Razer HID class driver upgrade. do you also use razer keyboard or device aswell? because this is the only one windows update history i get.
So I was having this same issue, what worked for me was disabling Virtual Based Security on my Windows 10 1909 host machine. Now I'm able to boot my vm.
I opened local group policy and browsed to - Computer Configuration\Administrative Templates\System\Device Guard. I then set "Turn on Virtualization Based Security" to Disabled. Not sure if a restart is needed, I restarted anyway just in case. Hope that helps.
After many hours of troubleshooting and many attempted fixes I finally got my VM working again by rolling back the Windows Update that came in the day before. It was a 'Security update for Windows' that somehow managed to mess up my host to VMware relationship. For the record all of the following didn't work for me:
I was about to give up and just wait until I could safely upgrade my Windows build when I thought that it could have been to do with the windows update which I did yesterday so rolled it back and the VM worked fine Player 15 and 16.
Microsoft Windows 10 Home
Version 10.0.18363 Build 18363
Hope this can help some others with the very annoying issue
This issue is caused because the system does not meet certain minimum requirements. VMware Workstation and VirtualBox don't work together with Hyper-V. These applications might not start virtual machines, or they may fall back to a slower, emulated mode.
