Hi guys,
I've been banging my head against a wall getting a Nvidia Tesla T4 passthrough-enabled VM to boot. I have two ESXi hosts in a Vsphere 8.0.0 setup (Enterprise Plus), each with 1 T4 card. These systems previously each ran a Quadro P620 via passthrough without issues. Moving to the T4 has been nothing but trouble.
With either ESXi host, it properly boots and recognizes the card, and I am able to enable passthrough on it in the vSphere UI, as well as add it to a VM configuration. However, once I try to start the VM (on either host), it will hang at 88% and eventually error out. vmware.log for the VM shows:
Some more things:
The host systems are each a Supermicro SuperServer 5019D-FN8TP running an up-to-date BIOS (v1.8), and this model is listed as supporting the T4 according to Qualified Platform List for GPUs | Supermicro -- now, I do have the GPU plugged into a x16 riser, which converts it to the x8 PCIE slot on the motherboard, but the T4 spec sheet says it supports PCIE 3.0 x8 and x16 so I didn't think this would be an issue.
BIOS is as follows:
The GPU shows up in the Vsphere UI as follows:
The GPU shows up fine on the host via esxcli hardware pci list -c 0x300 -m 0xff:
Here's the .vmx file for the VM I'm trying to boot:
Items like svga.vramSize, vmotion.*, svga.present were added automatically by VMWare. If I change from DirectPath to Dynamic Directpath, the pciPassthru0 items become:
Thank you for any help on this matter! Would love to get these cards working over the Quadros.

- The VM is set to boot via EFI and boots up fine without the GPU passthrough device added - stock Ubuntu 22.04 install.
- I've tried both DirectPath IO and Dynamic DirectPath IO to pass the card though, no difference.
- Embedded virtualization is not enabled in the vm.
- All VM memory is reserved.
- I have also tried enabling and disabling the IOMMU in the VM (under CPU).
- Tried autodetecting the video card, and manually specifying it.
- Have tried restarting the host after enabling passthrough...have rebooted the host numerous times.
