Hi,
I have some issues with NVIDIA vGPU functionality. I followed this guide and everything is working fine : I tested both Linux and Windows VM.
However, when starting the VM, these errors are shown
I exchanged with Gigabyte support (the manufacturer of the server) and confirmed that BIOS settings are correct (BIOS is up to date as well) :
- PCI AER and ARI are enabled
- SR-IOV and IOMMU are enabled
- ReBAR is enabled
Here is the configuration of the VM
Here are the packages version
The NVIDIA vGPU driver version is
The card is an NVIDIA RTX Pro 6000
Running kernel version is
How can I fix the error mentionned above ?
