PVSCSI drivers not signed

Hi everyone,

I try to create a Windows Server 2019 template with VMware Paravirtual SCSI controller.

As Windows Server 2019 installer does not have PVSCSI driver, I need to load it manually from VMware Tools iso image during the installation process.

When I browse to D:\Program Files\VMware\VMware Tools\Drivers\pvscsi\Win10\amd64 to select the driver, I have an error message saying "No signed device drivers were found".

The problem exists since VMware Tools 12.0.5 (with PVSCSI drivers

In VMware Tools 12.0.0 (PVSCSI driver, there is no problem.

Drivers in D:\Program Files\VMware\VMware Tools\Drivers\pvscsi\Win8\amd64 seems correctly signed as well.

Please VMware Team, can you sign PVSCSI driver and update VMware Tools?



VMware Infrastructure: VMware vSphere

ESXi version: VMware ESXi, 7.0.3, 20328353

VMware Tools version: 12325 (12.1.5)


Steps to reproduce:

  • Create a VM with VMware Paravirtual SCSI controller
  • Boot on Windows Server 2019 iso file
  • During the installation process, you couldn't see any disk drive to install Windows. Click on "Load driver" and browse to D:\Program Files\VMware\VMware Tools\Drivers\pvscsi\Win10\amd64


Expected results:

VMware PVSCSI driver loads correctly.


Actual results:

Unable to load PVSCSI driver with this error message: No signed device drivers were found

I ran into this problem as well and ended up using the Win8 drivers as those were signed.


Whew - glad I'm not the only going what the heck happened! 

Same issue here try to setup a windows 10 golden image.

@robinsonjl3 Personally, as I don't really know the difference between Win8 and Win10 drivers, I'm using an old version of the VMware Tools (12.0.0) during the Windows installation, then I'm upgrading VMware Tools through the vCenter interface.

Confirmed - I saw the same thing.  The instructions at https://techzone.vmware.com/resource/manually-creating-optimized-windows-images-vmware-horizon-vms#i... do NOT match up to reality for me.  I'm going to try the Win8 drivers (which DO appear) and hope for the best.

The Win10 version is for 10.0.20124 and later (Windows 11 21H2), the Win8 version is for Windows 8.0/8.1 and Windows 10/Server 2016/Server 2019.

A bit confusing, but you can see it in the .inf file:

; Build for 3 different driver versions that support Windows versions:
; - 6.0 and 6.1
; - 6.2, 6.3, 10.0 but not 10.0.20124 and later.
; - 10.0.20124 and later

We'll add some text to the techzone guide to clarify it.
