Hello @Simon-Zh-0409 ; for this release we do not support pci device passthrough;

@Simon-Zh-0409 - It would be good if you can provide details of your use case though.

@bktan8 As i can read; the use case is to passthrough the NVMe; which kind of other information would you expect ?

I'm looking for higher level use case idea. Need more business justifications.

GPU passthrough for NVIDIA CC is a good use case.
