Preface: Virtio-net device emulation enables users to create VirtIO-net emulated PCIe devices in the system where the NVIDIA® BlueField® DPU is connected.

Background: The Intelligent Platform Management Interface (IPMI) is a standard interface for hardware management used by system administrators to control the devices and monitor the sensors. For these, it is necessary the IPMI Controller called Baseboard Management Controller (BMC) and a manager software (for example, IPMItool).
