8. 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.

You must complete all the steps in the Getting Started and Installing the OPAE Software chapters before you can set up a virtualized environment. 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.
sudo fpgasupdate \
