docs: import the operator guides that lived in the cozystack repo - #648
Merged
Conversation
Four guides had been written into cozystack/cozystack under docs/ as part of the feature PRs that added the code, and never routed anywhere a user would look. They are operator-facing how-tos with no reason to sit in the source tree, so move them here, into both next/ and v1.6/. New pages: - virtualization/vgpu.md — NVIDIA vGPU on the vgpu variant: the two host driver models, building the vGPU Manager image, SR-IOV profile assignment, DLS licensing, the L40S profile table, OS support. - operations/troubleshooting/gpu-operator-host-driver.md — the passthrough variant refusing to bind vfio-pci when the host already carries an apt-installed driver. This was a 120-line troubleshooting runbook wedged inside the vGPU guide; it is its own problem and now its own page. - networking/vm-external-vlan.md — bridging a VM onto a physically routed VLAN, and why macvlan cannot work with KubeVirt bridge binding. The CNI-plugin staging contract that shared that document stays in the cozystack repo, as packages/system/multus/README.md, because a bats suite asserts its prose against the Dockerfile and the manifest. - networking/hubble.md — enabling Hubble, plus the four dashboards Cozystack ships for it. Stale and PR-shaped content dropped rather than carried over: a "Last verified ... this PR's vgpu variant" stamp, and two claims that the container variant was unmerged (it landed in cozystack#2766 last June, so the runbook now points at it as the no-purge alternative). NVIDIA/k8s-driver-manager#191 was re-checked and is still open. Two corrections to existing pages while wiring them up. virtualization/ gpu.md said vGPU "uses mediated devices (mdev)", which is only true up to Ampere — Ada Lovelace and newer use SR-IOV virtual functions. networking/hubble.md notes that the dashboards are provisioned from dashboards-infra.list, which renders only for tenant-root and cozy-monitoring, so they appear in the platform Grafana and not in a tenant's own.

These four guides were written into cozystack/cozystack under
docs/inside the feature PRs that added the code, and never routed anywhere a user looks. They are operator facing how-tos with no reason to sit in the source tree, so I moved them here, into bothnext/andv1.6/.New pages
virtualization/vgpu.md- NVIDIA vGPU on the vgpu variant: two host driver models, building the vGPU Manager image, SR-IOV profile assignment, DLS licensing, L40S profile table, OS support.operations/troubleshooting/gpu-operator-host-driver.md- passthrough variant refusing to bind vfio-pci when the host already carries an apt installed driver. This was a 120 line runbook wedged inside the vGPU guide, it is its own problem so it gets its own page.networking/vm-external-vlan.md- bridging a VM onto a physically routed VLAN, and why macvlan does not work with kubevirt bridge binding.networking/hubble.md- enabling hubble, plus the four dashboards cozystack ships for it.Dropped stale content instead of carrying it over: a "Last verified ... this PR's vgpu variant" stamp, and two claims that the container variant is unmerged (it landed in cozystack/cozystack#2766 last June, so the runbook points at it as the no-purge alternative now). Rechecked NVIDIA/k8s-driver-manager#191, still open.
Two fixes to existing pages while wiring the links.
virtualization/gpu.mdsaid vGPU uses mediated devices, that is only true up to Ampere, Ada Lovelace and newer use SR-IOV virtual functions. And the hubble dashboards come fromdashboards-infra.list, which renders only for tenant-root and cozy-monitoring, so they appear in the platform grafana and not in a tenant's own.The CNI plugin staging contract that shared the vm-external-vlan document stays in cozystack/cozystack as
packages/system/multus/README.md, because a bats suite asserts its prose against the Dockerfile and the manifest. Deletion of the originals is a separate PR there, i'll link it once it is open.
