Attaching physical PCI devices to virtual machines

By attaching various PCI devices from compute nodes to virtual machines, you can reduce VM network latency or accelerate visualization inside a guest operating system. PCI device passthrough is available only on servers that support Input/Output Memory Management Unit (IOMMU). For a list of IOMMU-supporting hardware, refer to this article.

You can attach the following PCI devices:

To attach a physical PCI device to a virtual machine, follow these steps:

Steps for HBA passthrough are similar to those for GPU passthrough.

  1. Prepare compute nodes for PCI passthrough.
  2. Reconfigure the compute cluster to enable PCI passthrough.
  3. Create virtual machines with attached PCI devices.
