KubeVirt DRA PCI Driver

This repository holds currently a Proof of Concept and DRA isn't currently supported by KubeVirt

This repository contains a Dynamic Resource Allocation (DRA) device driver for PCI passthrough devices to be used with KubeVirt.

About the Resource Driver

The KubeVirt DRA Driver is designed as an alternative to the device-plugin framework-based host device management in KubeVirt's virt-handler. It provides better control over devices on KubeVirt VMs by leveraging the Dynamic Resource Allocation (DRA) framework in Kubernetes.

Prerequisites

• GNU Make 3.81+
• GNU Tar 1.34+
• Docker v20.10+ (including buildx)

Documentation

• Install and Use KubeVirt with the DRA PCI Driver
• How to Change and Rebuild the Driver

Prior Art

• kubernetes-sigs/dra-example-driver provides a practical implementation of how a resource entity should be handled to ensure proper scheduling of Pods according to resources present in a Node.
• Device Manager Implementation from KubeVirt provides an implementation of handling several devices, including PCI devices for VMIs, using the device-plugin framework as part of virt-handler.
