Addresses follow-up review of the vGPU variant + chart bump.
* values.yaml: pin ccManager.enabled=false and vgpuDeviceManager.enabled=false.
Upstream chart v26.x flipped both to true. ccManager auto-enables CC
mode on Hopper-class hardware after upgrade — a non-trivial behavior
change that should be opt-in. vgpuDeviceManager walks
/sys/class/mdev_bus/, which does not exist on Ada+ (L4/L40/L40S/B100
with vGPU 17/20). Pinning both off keeps the default footprint as it
was on v25.x; users explicitly opt in.
* hack/dcgm-default-counters.csv: refresh from dcgm-exporter tag
4.5.1-4.8.0 (matches the image bumped earlier in this PR). The
previous snapshot was pinned to 4.1.1-4.0.4. Adds DCGM_FI_DEV_FB_RESERVED
and other fields introduced upstream. Header comment updated.
hack/check-gpu-recording-rules.bats passes against the refreshed
fixture.
* docs/gpu-vgpu.md (Licensing section):
- Drop the wrong recommendation to wire the licensing Secret through
gpu-operator's driver.licensingConfig.secretName. That mounts into
the host driver pod, where SR-IOV vGPU does not consume a license.
Document guest-side delivery (cloud-init write_files for
/etc/nvidia/ClientConfigToken/ and /etc/nvidia/gridd.conf) end to
end.
- Correct FeatureType comment. Per the NVIDIA Virtual GPU Software
Licensing User Guide, FeatureType=0 is the unlicensed state, not
auto-detect; FeatureType=1 is the value that asks the driver to
auto-select the license type from the configured vGPU profile.
Switch the example to FeatureType=1 and list all four valid values
with their meaning.
- Add nvidia-smi verification snippet inside the guest.
* docs/gpu-vgpu.md (KubeVirt section): note that L40S SR-IOV VFs share
the PF device ID (10de:26b9), so a single pciVendorSelector matches
both. Recommend lspci -nn -d 10de: as a sanity check on other
generations where PF/VF IDs may differ.
