7. Running the OPAE in a Virtualized Environment

In SR-IOV mode, a host processor uses a physical function (PF) to access management functions. A virtual machine (VM) uses a virtual function (VF) to access the AFU.
Note: Partial reconfiguration (PR) is not available in this mode.
Figure 5. OPAE Driver in SR-IOV Mode

An application running in a virtual machine that connects to a VF through OPAE cannot initiate partial reconfiguration. The permission table in the FME enforces this restriction. The permission table only allows partial reconfiguration through a PF. Consequently, you must load the AFU image on the host before continuing with the steps to create a virtualized environment.

Run the following command on the host to load the AFU image on a board with no root entry hash programmed.

sudo fpgasupdate \
$OPAE_PLATFORM_ROOT/hw/samples/nlb_mode_0/bin/nlb_mode_0_unsigned.gbs
