Hi everyone,
I’m running Proxmox VE 8.0 and recently set up a Windows 11 VM with GPU passthrough (NVIDIA GeForce RTX 3070). Everything seemed to work fine at first, but now I get a BSOD (Driver Verifier Detected Violation) within a few minutes of starting the VM. The guest OS reboots automatically with no dump file, and the host logs show this:
nov 123 Loading driver verifier...
Win32kFull!xxx.vyxx+0×12345
What I’ve tried so far:
- Updated Proxmox to the latest patches
- Ensured IOMMU is enabled with
intel_iommu=on - Passed through only the GPU (no audio device)
- Tested with both Q35 and OVN machine types
- Disabled Hyper-V features in Windows
- Used both official NVIDIA and Nouveau drivers
Still the VM crashes reliably.
Questions:
- Has anyone else seen BSODs in Win11 VMs using GPU passthrough?
- Are there specific kernel or BIOS settings known to cause—or fix—this issue?
- Any logs or Windows tools I should enable to get more helpful dumps?

Thanks in advance for your guidance.
