NFD Libvirt is a feature which runs node-feature-discovery and libvirt containers
in the same pod. Libvirt container runs virsh domcapabilities --machine q35 --arch x86_64 --virttype kvm command and output saves into /usr/share/virsh/virsh-domcapabilities.xml file. Folder /usr/share/virsh is shared between NFD and libvirt container.
Usage:
kubectl create -f node-feature-discovery-libvirt-daemonset.yaml.template
kubectl exec -it <pod name> --container node-feature-discovery -- cat /usr/share/virsh/virsh-capabilities
Future plans: Parse libvirt output and integrate it into NFD - nfd-host-supported-cpus
