Load the Virtual SCSI pass-through controller.
The error message shown in the image indicates that Windows 10 setup cannot find any drives to install the OS. This is because the Nutanix AHV hypervisor uses a virtual SCSI pass-through controller to present disks to the VMs, and Windows 10 does not have a built-in driver for this device. Therefore, the administrator needs to load the Nutanix VirtIO driver for the virtual SCSI pass-through controller during the OS installation process. The Nutanix VirtIO driver package contains various drivers that are specifically used by Windows VMs hosted in the Nutanix environment to enhance their stability and performance1. The administrator can download the latest Nutanix VirtIO driver package from the VirtIO downloads page of the Nutanix support portal. The administrator can then follow these steps to load the driver and install the OS2:
On the Windows 10 setup screen, click Load driver.
Insert a USB drive or mount an ISO image that contains the Nutanix VirtIO driver package.
Browse to the location of the driver package and select the folder that matches the OS architecture (32-bit or 64-bit).
Select the vioscsi.inf file and click Next.
Wait for the driver to load and then click Refresh.
Select the disk where you want to install Windows 10 and click Next.
