VirtIO SCSI driver is not compatible with Windows 11 IoT Enterprise LTSC 2024

[Turbine8845]

Describe the bug I am using a Windows 11 Pro 24H2 host machine and am trying to install Windows 11 IoT Enterprise LTSC 2024 on a VirtualBox VM. I selected VirtIO-SCSI as the controller type in the VM's settings. During the installation of Windows 11 IoT Enterprise LTSC, the VirtIO SCSI pass-through drivers are not displayed as compatible drivers. Unchecking the Hide drivers that are not compatible... option allows me to select and install the VirtIO-SCSI drivers, and after installation, I can see the virtual disk. However, I cannot partition the virtual hard disk, and I am unable to proceed with the installation of Windows 11 IoT Enterprise LTSC 2024. I have attached some screenshots showing the issues I am encountering with Windows 11 IoT Enterprise LTSC 2024. I am using virtio-win-0.1.262.iso for this VM. I did not experience this issue with earlier versions of Windows.

To Reproduce

1. Download the official non-evaluation version of Windows 11 IoT Enterprise LTSC 24H2: File name: en-us_windows_11_iot_enterprise_ltsc_2024_x64_dvd_f6b14814.iso SHA256: 4F59662A96FC1DA48C1B415D6C369D08AF55DDD64E8F1C84E0166D9E50405D7A

2. Select the controller type for the Windows ISO and the VirtIO ISO as SATA or AHCI.

3. Attempt to install Windows 11 IoT Enterprise LTSC on the VM using the latest VirtIO drivers, virtio-win-0.1.262.iso. You will encounter the errors shown in the attached screenshots.

Expected behavior VirtIO SCSI pass-through drivers should be visible during the installation of Windows as compatible drivers.

Screenshots

1. VirtIO SCSI pass-through drivers not detected as compatible during the installation of Windows 11 IoT Enterprise LTSC 2024

2. VirtIO SCSI pass-through drivers are shown after unchecking Hide drivers...

3. Virtual disk is detected after installing the incompatible VirtIO SCSI pass-through driver

4. The detected virtual disk cannot be partitioned, and installation cannot proceed

Host:

• OS Name: Microsoft Windows 11 Pro 24H2 (Build 2610.2033)
• Kernel version: 10.0.26100
• VirtualBox Version: 7.1.4 r165100

VM:

• Windows version: Windows 11 IoT Enterprise LTSC 2024
• Which driver has a problem: VirtIO SCSI pass-through driver
• Driver version or commit hash that was used to build the driver: virtio-win-0.1.262

Additional context This issue occurs on a Windows 11 Pro 24H2 host using VirtualBox 7.1.4. I am reporting this to determine if the problem is related to these environments or the VirtIO drivers themselves. At the moment, I don't have access to my Linux machine. I will run some tests using QEMU/KVM to see if the same issue occurs.

@YanVugenfirer @vrozenfe Looks like a duplicate of https://github.com/virtio-win/kvm-guest-drivers-windows/issues/1100. What do you think?

Thank you for reporting the issue. Can you try installing drivers from Win10 sub-directory ?

Best, Vadim.

Best, Vadim.

Thank you for your response. I tried installing the drivers from w11, w10, and w2k25, sub-directories inside the amd64 directory but I experienced the same issues that I reported earlier. Apart from Windows 11 IoT LTSC, the regular Windows 11 24H2 iso doesn't recognize the VirtIO SCSI pass-through drivers inside the virtio-win-0.1.262 iso as compatible either. I didn't have this problem with 23H2.

and it seems to be working fine:

By any chance can you installing Win11 on an emulated system drive and then attach a virtio drive as a secondary/data disk and try to install virtio driver on that disk?

Thanks, Vadim.

I tried this and I managed to successfully install the driver.

I really have no idea why I encountered those errors during the installation of Windows 11. I guess I configured my VM correctly. Maybe only VirtualBox is affected. I will try QEMU.
