Enabling Support for PCI Passthrough

This section describes how to enable a VM to support PCI Passthrough.

If the VM uses the SR-IOV mechanism, then ensure that the VF number for the associated PF and MAC address is available.

Use the following configuration to configure the PCF passthrough option on the VM:

cluster cluster_name 
   nodes node_name 
      type kvm 
         os enable-passthrough  {true|false} 
         os num-vfs-per-pf number_of_vf_per_pf 
   exit 
exit 

NOTES:

  • cluster cluster_name – Specify the name of the cluster.

  • nodes node_name – Specify the name of the node.

  • os enable-passthrough {true|false} – Configures the PCI passthrough capability for the VM. Default value is "false".

  • os num-vfs-per-pf number_of_vf_per_pf – Specifies the number of the VF for each physical function. Default value is 16.
