Single root I/O virtualization (SR-IOV) allows
a single PCIe physical device under a single root port to appear
to be multiple separate physical devices to the hypervisor or guest.
Enable SR-IOV by enabling virtual function devices on the SR-IOV
NIC and the modify the guest settings in vCenter.
method, which is preferred for PAN-OS 8.1.2 and later, allows you
to add the SR-IOV PF to a vSwitch or DvSwitch.
—This method was required
for PAN-OS 8.0 through 8.1.1. You can view the PCI Adaptor workflow
in Enable SR-IOV on ESXi in
the 8.1 Deployment Guide.
The PCI Adaptor method has the limitation
that you cannot configure a vSwitch on the physical port on which
you enable SR-IOV. The VM-Series firewall must have exclusive access
to the physical port and associated virtual functions (VFs) on that
interface so it can communicate with the host or other virtual machines on
the network. Refer to Add a PCI Device in the vSphere
