Libvirt provides management of both physical and virtual host devices (historically also referred to as node devices) like USB, PCI, SCSI, and network devices. This also includes various virtualization capabilities which the aforementioned devices provide for utilization, for example SR-IOV, NPIV, MDEV, DRM, etc.

The node device driver provides means to list and show details about host devices (virsh nodedev-list, virsh nodedev-dumpxml), which are generic and can be used with all devices. It also provides means to create and destroy devices (virsh nodedev-create, virsh nodedev-destroy) which are meant to be used to create virtual devices, currently only supported by NPIV (more info about NPIV)). Devices on the host system are arranged in a tree-like hierarchy, with the root node being called computer. The node device driver supports udev backend (HAL backend was removed in 6.8.0).

Details of the XML format of a host device can be found here. Of particular interest is the capability element, which describes features supported by the device. Some specific device types are addressed in more detail below.

Basic structure of a node device

  • PCI host devices
capability
When used as top level element, the supported values for the type attribute are pci and phys_function (see SR-IOV below).

The XML format for a PCI device stays the same for any further capabilities it supports, a single nested <capability> element will be included for each capability the device supports.

Single root input/output virtualization (SR-IOV) allows sharing of the PCIe resources by multiple virtual environments. That is achieved by slicing up a single full-featured physical resource called physical function (PF) into multiple devices called virtual functions (VFs) sharing their configuration with the underlying PF. Despite the SR-IOV specification, the amount of VFs that can be created on a PF varies among manufacturers.

Suppose the NIC above was also SR-IOV capable, it would also include a nested <capability> element enumerating all virtual functions available on the physical device (physical port) like in the example below.

A SR-IOV child device on the other hand, would then report its top level capability type as a phys_function instead:

A device capable of creating mediated devices will include a nested capability mdev_types which enumerates all supported mdev types on the physical device, along with the type attributes available through sysfs. A detailed description of the XML format for the mdev_types capability can be found here.

The following example shows how we might represent an NVIDIA GPU device that supports mediated devices. See below for more information about mediated devices.

Mediated devices (Since 3.2.0) are software devices defining resource allocation on the backing physical device which in turn allows the parent physical device's resources to be divided into several mediated devices, thus sharing the physical device's performance among multiple guests. Unlike SR-IOV however, where a PCIe device appears as multiple separate PCIe devices on the host's PCI bus, mediated devices only appear on the mdev virtual bus. Therefore, no detach/reattach procedure from/to the host driver procedure is involved even though mediated devices are used in a direct device assignment manner. A detailed description of the XML format for the mdev capability can be found here.

Example of a mediated device

The support of mediated device's framework in libvirt's node device driver covers the following features:

Driver
  • list available mediated devices on the host (Since 3.4.0)
  • display device details (Since 3.4.0)

Because mediated devices are instantiated from vendor specific templates, simply called 'types', information describing these types is contained within the parent device's capabilities (see the example in PCI host devices).

Devices

To see the supported mediated device types on a specific physical device use the following:

Before creating a mediated device, unbind the device from the respective device driver, eg. subchannel I/O driver for a CCW device. Then bind the device to the respective VFIO driver. For a CCW device, also unbind the corresponding subchannel of the CCW device from the subchannel I/O driver and then bind the subchannel (instead of the CCW device) to the vfio_ccw driver. The below example shows the unbinding and binding steps for a CCW device.

To manually instantiate a mediated device, use one of the following as a reference. For a CCW device, use the subchannel ID instead of the device ID.

Manual removal of a mediated device is then performed as follows:
