The PCNet FAST III is the default because it is supported by nearly all operating systems, as well as by the GNU GRUB boot manager. As an exception, the Intel PRO/1000 family adapters are chosen for some guest operating system types that no longer ship with drivers for the PCNet card, such as Windows Vista.
The Paravirtualized network adapter (virtio-net) is special. If you select this adapter, then Oracle VM VirtualBox does not virtualize common networking hardware that is supported by common guest operating systems. Instead, Oracle VM VirtualBox expects a special software interface for virtualized environments to be provided by the guest, thus avoiding the complexity of emulating networking hardware and improving network performance. Oracle VM VirtualBox provides support for the industry-standard virtio networking drivers, which are part of the open source KVM project.
Neither virtio nor Intel PRO/1000 drivers for Windows XP support segmentation offloading. Therefore Windows XP guests never reach the same transmission rates as other guest types. Refer to MS Knowledge base article 842264 for additional information.
The PCNet FAST III is the default because it is supported by nearly all operating systems out of the box, as well as the GNU GRUB boot manager. As an exception, the Intel PRO/1000 family adapters are chosen for some guest operating system types that no longer ship with drivers for the PCNet card, such as Windows Vista.
The "Paravirtualized network adapter (virtio-net)" is special. If you select this, then VirtualBox does not virtualize common networking hardware (that is supported by common guest operating systems out of the box). Instead, VirtualBox then expects a special software interface for virtualized environments to be provided by the guest, thus avoiding the complexity of emulating networking hardware and improving network performance. Starting with version 3.1, VirtualBox provides support for the industry-standard "virtio" networking drivers, which are part of the open-source KVM project.
[31] For Mac OS X and Solaris hosts, net filter drivers were already added in VirtualBox 2.0 (as initial support for Host Interface Networking on these platforms). With VirtualBox 2.1, net filter drivers were also added for the Windows and Linux hosts, replacing the mechanisms previously present in VirtualBox for those platforms; especially on Linux, the earlier method required creating TAP interfaces and bridges, which was complex and varied from one distribution to the next. None of this is necessary anymore. Bridged network was formerly called "Host Interface Networking" and has been renamed with version 2.2 without any change in functionality.
It had been reported that GENGRADD, VBOXGRADD, SNAP and Panorama drivers may work on the guest virtual machine. But SNAP and Panorama are not really necessary and may be generating some little overhead according to some opinions. So it may be recommended to use GENGRADD or VBOXGRADD.
The industry standard virtIO networking drivers are supported by VirtualBox. VirtIO networking drivers are a part of the KVM project and are open-source. These drivers are available for Linux with kernel 2.6.25 or later, and Windows including older versions such as Windows 2000, XP and Vista.
A dialog box similar to the original window now appears with drop-down menus for each of the hardware components. The Display drop-down will currently show VGA. A long list of video drivers that come standard with Windows will appear, however are not compatible with VirtualBox. Scroll your way down until the option Other display (Requires disk from OEM) is chosen. Windows Setup will now request for the floppy disk containing the video card drivers. Load up the disk image with those drivers.
Installing drivers with Windows 3.x was never consistent, the video and network cards via Windows Setup, the sound card via the Control Panel or in DOS itself. For VirtualBox double check that the sound settings for the VM itself are set to SoundBlaster 16 as this is the sound card to be emulated. Grab a copy of the SoundBlaster 16 drivers for DOS, and totally exit out of Windows. Insert the sound driver disk image and type at the C:\> prompt a:\install and press Enter to load the installation program.
It will go through a series of steps such as where to install the drivers and configuration settings which can all be left with the default options. As Windows is installed, the program will recognise this and ask whether a config file is to be backed up before being replaced. Choose Backup.
Once you reach the end of the installation process, restart the VM in order for the sound drivers to be loaded. When you return back to Windows, a new program group will appear named Audio Software with the Creative Mixer program available for use. Creative Mixer works much the same as Volume Control that became available with Windows 95 onwards.
Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.

This article introduces VirtualBox research and explains how to build a coverage-based fuzzer, focusing on the emulated network device drivers. In the examples below, we explain how to create a harness for the non-default network device driver PCNet. The example can be readily adjusted for a different network driver or even different device driver components.
Running kmk without KBUILD_TYPE yields instrumented binaries, where the device drivers are bundled inside VBoxDD.so shared object. The output from nm confirms the presence of the instrumentation symbols:
At this point, the VirtualBox drivers are fully instrumented, and the only remaining thing left before we start fuzzing is a harness. The PCNet device driver is defined in src/VBox/Devices/Network/DevPCNet.cpp, and it exports several functions. Our output is truncated to include only R3 components, as these are the ones we are targeting:
For the network drivers, there are various ways of supplying the user-controlled data by using access I/O port instructions or reading the data from the emulated device via MMIO (PDMDevHlpPhysRead). If this part is unclear, please refer back to [1] in references, which is probably the best available resource for explaining the attack surface. Moreover, many ports or values are restricted to a specific set, and to save some time, we want to use only these values. Therefore, after some consideration for the implementing of our fuzzing framework, we discovered Fuzzed Data Provider (later FDP).
All device drivers have a state, which we can access using convenient macro PDMDEVINS_2_DATA. Likewise, we can extend the state structure (in our case PCNETSTATE) to include the FDP header file via a pointer to FDP:
Additionally, we can disable the instantiation of all devices which we are not currently fuzzing. The relevant code is inside src/VBox/VMM/VMMR3/PDMDevice.cpp, implementing the init completion routine through pdmR3DevInit. For the PCNet driver, at least the pci, VMMDev, and pcnet modules must be enabled. Therefore, we can skip the initialization for the rest.
The most significant issue is that minimizing our test cases is not an option when the stability is low (the percentage depends on the drivers we fuzz). If we cannot reproduce the crash, we can at least intercept it and analyze it afterward in gdb. 2b1af7f3a8
