Description
There is a virtual PCI bus on Z systems, but the kernel needs to be recent, and tooled to expose it/use it.
What happened:
No PCI features or facts about the virtual PCI bus on system Z are exposed
What you expected to happen:
NFD should at least tell us the status of the Z node's virtual PCI bus.
How to reproduce it (as minimally and precisely as possible):
- Install and run NFD Operator on OCP on System Z, either KVM or z/VM.
- Observe that no PCI features are discovered
Environment:
- Kubernetes version (use
kubectl version): browser - Cloud provider or hardware configuration: Z15 KVM Cluster
- OS (e.g:
cat /etc/os-release): RHEL 8.3

Research direction
Start by reproducing the issue with the NFD Operator on OCP on System Z using KVM or z/VM, then inspect how PCI feature discovery handles the virtual PCI bus on the Z15 KVM and RHEL 8.3 environment. Done means NFD exposes the virtual PCI bus status or related PCI facts for the node.
