Single Root I/O Virtualization (SR-IOV) allows a single physical NIC to appear as multiple
physical NICs. All NICs in the VM must be tagged to the appropriate VLAN.
The two SR-IOV functions are as follows:
Physical Function (PF) - Physical Ethernet
controller that supports SR-IOV
Virtual Function (VF) - Virtual device created
from a physical Ethernet controller
The following figure shows a network with:
ens3f1 (Compute-1) and ens3f0 (Compute-2) as
part of network for PF-PT
ens3f0 (Compute-1) and ens2f0 (Compute-2) as part of network for VF-PT
