In Shared NVSwitch Multitenancy Mode - are there any considerations for leveraging infiniband devices inside each vm at full performance?

We haven't looked deeply at inter-machine communication yet. NVLink/NVSwitch (which this post focuses on) are intra-node, so InfiniBand is mostly orthogonal I think and comes down to NIC passthrough, NUMA/PCIe placement, and validating RDMA inside the VM.
