The KubeVirt provider is the reference implementation for Conformance EE’s provider system. It handles infrastructure discovery and spec generation for KubeVirt-based clusters.
The provider queries the KubeVirt infrastructure cluster to enumerate available resources:
| Resource | API Group | Description |
|---|---|---|
| VPCs | kubeovn.io/v1 |
Virtual private cloud networks |
| Subnets | kubeovn.io/v1 |
Network subnets (paired with parent VPC) |
| StorageClasses | storage.k8s.io/v1 |
Available storage backends |
| Instance Types | instancetype.kubevirt.io/v1beta1 |
VirtualMachineInstancetype resources |
| Preferences | instancetype.kubevirt.io/v1beta1 |
VirtualMachinePreference resources |
These discovered resources are converted into dynamic modifiers that expand the test matrix based on what’s actually available in the target environment.
The KubeVirt provider supports the following OS distributions for virtual machine disks:
| Distribution | Supported Versions |
|---|---|
| Ubuntu | 20.04, 22.04 |
| RHEL | 8, 9 |
| Flatcar | 3374.2.2 |
| Rocky Linux | 8, 9 |
Custom image sources can be configured via the imageSources field in the configuration file.
