Hello,
I would like to ask if it is possible to create Virtual Functions inside of a VM. In our case we passthrough Bluefield into the VM then create Virtual Functions inside VM Host attach them into nested VMs. Below is a visual to describe our setup:
The problem is without passthrough we can observe sriov_numvfs under sys/class/net//device just fine however when it is passthrough to VM sriov_numvfs is not present inside VM.
Summary:
Attempted:
- Creating Virtual Functions inside VM Host according to https://docs.nvidia.com/doca/sdk/nvidia+doca+virtual+functions+user+guide
Expected:
- Being able to see and change sriov_numvfs under sys/class/net//device
Result:
- sriov_numvfs is not present when Bluefield is passthrough to VM Host but is present when it is in Main Host
Note : When we query mellanox config our VF creation is marked as next boot.
Thanks in advance,
Best Regards.
