Code Review
This pull request introduces a new firmware configuration block for virtual machine instances, allowing users to select the bootloader ("uefi" or "bios"), enable UEFI Secure Boot, and persist EFI NVRAM. This configuration is integrated into the Go API types, Helm chart templates, values schema, and documentation. The reviewer suggested two improvements: defining the bootloader field as an enum type in values.yaml to automatically generate validation schemas and typed Go APIs, and simplifying the Helm template logic in vm.yaml by removing redundant toString conversions and unnecessary default values for boolean checks.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

We can define Bootloader as an enum type using the repository's generator annotations. This will automatically generate the corresponding enum validation in values.schema.json and a typed string in the Go API types, preventing invalid values or typos.

We can simplify the template conditions by removing the redundant toString calls. In Go/Helm templates, eq can safely compare any type with a string (returning false if it is nil), so toString is unnecessary. Additionally, since $fw.secureBoot is a boolean, we can use it directly in the and condition without | default false.

Constrain bootloader to allowed values at the API type level.
At Line 82, Bootloader is unconstrained string; invalid values can pass validation and then be ignored by template branches that only handle "uefi"/"bios", resulting in surprising runtime config. Please add kubebuilder enum validation (or a dedicated typed enum) so invalid input is rejected early.
As per coding guidelines **/*.go should follow kubebuilder conventions, and based on learnings enum consistency should be enforced from source definitions rather than post-generated artifacts.

NOT LGTM — firmware.bootloader accepts arbitrary strings, so a typo silently disables a security control (Secure Boot) instead of erroring; the persistent-EFI warning also understates its operational impact on node drains.
Business context: Adds a per-VM firmware block (UEFI/BIOS, Secure Boot, persistent EFI NVRAM) to VMInstance so boot firmware can be set directly rather than only via the OS instanceProfile.
The firmware/SMM rendering itself is correct: secureBoot is always emitted explicitly (avoiding KubeVirt's default-true behavior), and features.smm.enabled is emitted exactly when bootloader=uefi and secureBoot=true, satisfying KubeVirt's "SMM required for Secure Boot" constraint. Generated artifacts (deepcopy, cozyrds schema, README) are in sync. Two changes requested before merge.
Blockers
B1: bootloader is an unconstrained string — invalid values silently disable Secure Boot
File: api/apps/v1alpha1/vminstance/types.go:82 (and packages/apps/vm-instance/values.yaml)
Issue: Bootloader is a free string with no enum. A value the template doesn't recognize ("UEFI", "ovmf", a typo) passes schema validation, matches neither the uefi nor bios branch in templates/vm.yaml, and silently falls back to the instanceProfile default — no error.
Impact: A user who sets bootloader: UEFI + secureBoot: true believes Secure Boot is enabled; it is not, and there is no signal. The schema-driven dashboard also renders a free-text field instead of a dropdown, making the typo path the likely one.
Fix: Constrain to the two valid values in both schema sources:
types.go: add// +kubebuilder:validation:Enum=uefi;biosaboveBootloader(keep empty allowed for the inherit case).values.yaml: add an## @enumannotation forbootloaderso the generatedvalues.schema.jsonand thevm-instance-rdschema gain the constraint (and the UI renders a dropdown). Regenerate.
B2: the persistent-EFI warning understates the operational impact
File: api/apps/v1alpha1/vminstance/types.go:84 (propagates to values.yaml / README)
Issue: The efiPersistent doc says the VM "is node-pinned (no live-migration)." Because evictionStrategy: LiveMigrate is set cluster-wide, a non-migratable VM does not merely skip migration — it blocks node drains, which can stall rolling node maintenance and cluster upgrades. This is the same failure mode recently reverted out of the default instancetypes.
Impact: An operator enabling efiPersistent on a long-lived VM can unknowingly wedge a future cluster upgrade.
Fix: Extend the field doc (and README) to state that on default RWO storage the VM blocks node drains / can stall cluster upgrades, not only that it can't be live-migrated. Optionally note the RWX vmStateStorageClass path that lifts the restriction.
Non-blocking follow-ups
secureBoot/efiPersistentare silently ignored whenbootloaderis unset orbios. Documented as "only applies when uefi," but it is another silent no-op; B1's enum plus the doc wording mostly covers it — consider whether a values-level guard is worth adding.- Re: the suggestion to drop
toStringin theeqcomparisons — recommend keeping it: whenfirmware: {},bootloaderis nil andtoStringkeeps the comparison safe. - Labeling: the PR is
area/uncategorized; anarea/virtualization-style label fits the change better.

bootloader is an unconstrained string. A value the template doesn't match (UEFI, ovmf, any typo) passes schema validation and silently falls back to the instanceProfile default — so bootloader: UEFI + secureBoot: true produces a VM with Secure Boot off and no error.
Constrain it in both schema sources: add // +kubebuilder:validation:Enum=uefi;bios here, and an ## @enum annotation on bootloader in values.yaml so the generated values.schema.json and the vm-instance-rd schema also reject invalid input (and the dashboard renders a dropdown instead of free text). Keep empty valid for the inherit case.

This warning covers live-migration but not the larger impact: with cluster-wide evictionStrategy: LiveMigrate, a node-pinned persistent-EFI VM blocks node drains, which can stall rolling node maintenance and cluster upgrades. Please extend this doc (and the README) to say so — not just "no live-migration." Optionally mention the RWX vmStateStorageClass path that removes the pinning.

Two blocking findings from review, both against Forklift v2.11.5 sources. Plans carried no targetPowerState, so Forklift matched the source's power state (determineRunStrategy, pkg/controller/plan/kubevirt.go:3649). Every VM in a production cutover is running when it is migrated, so the target booted the moment the transfer finished: a duplicate of a live machine on the network, and a guest started on the volume the handoff was about to re-point. Pin it off (plan.TargetPowerStateOff, pkg/apis/forklift/v1beta1/plan/vm.go:27) and let the VMInstance be what starts the guest. Nothing read the source firmware, so a UEFI guest imported 'successfully' and did not boot — vm-instance grows a firmware field in #3002, and until then the rendered VM is BIOS regardless. Read the bootloader off the VirtualMachine the handoff already parses and fail that VM with a message naming the reason, instead of producing an unbootable instance.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Honor firmware flags when boot mode is inherited.
When instanceProfile: linux.efi is selected and firmware.bootloader is empty, this template emits only the profile preference; it does not render bootloader.efi, secureBoot, persistent, or SMM. As a result, secureBoot: true and efiPersistent: true are silently ignored. Resolve the effective boot mode before applying firmware flags, or reject these flags unless bootloader is explicitly uefi, and add a render test for inherited UEFI.

In `@packages/apps/vm-instance/templates/vm.yaml` at line 58, Update the
bootloader conditional around the firmware template so inherited UEFI profiles,
including instanceProfile linux.efi with an empty firmware.bootloader, use the
effective UEFI mode and render bootloader.efi, secureBoot, persistent, and SMM
consistently with the profile defaults. Alternatively reject secureBoot and
efiPersistent unless firmware.bootloader is explicitly uefi, and add a render
test covering the inherited-UEFI case.
Apply the same fix in `@packages/system/vm-instance-rd/cozyrds/vm-instance.yaml`
at line 11: The schema comment identifies the same inherited-UEFI Secure Boot
omission and is covered by the consolidated template-level finding.

Constrain firmware.bootloader to supported values.
The schema accepts any string, but the renderer handles only exact uefi and bios values. An input such as legacy passes validation and produces a VM without the requested bootloader. Add enum: ["", "uefi", "bios"] here and in packages/apps/vm-instance/values.schema.json.
This follows the supplied firmware schema and renderer contract.

Two blocking findings from review, both against Forklift v2.11.5 sources. Plans carried no targetPowerState, so Forklift matched the source's power state (determineRunStrategy, pkg/controller/plan/kubevirt.go:3649). Every VM in a production cutover is running when it is migrated, so the target booted the moment the transfer finished: a duplicate of a live machine on the network, and a guest started on the volume the handoff was about to re-point. Pin it off (plan.TargetPowerStateOff, pkg/apis/forklift/v1beta1/plan/vm.go:27) and let the VMInstance be what starts the guest. Nothing read the source firmware, so a UEFI guest imported 'successfully' and did not boot — vm-instance grows a firmware field in #3002, and until then the rendered VM is BIOS regardless. Read the bootloader off the VirtualMachine the handoff already parses and fail that VM with a message naming the reason, instead of producing an unbootable instance.

Hidora's customers are leaving VMware now, and a tenant has to be able to import their own machines without a platform administrator. The chart approach could not express that: a tenant can neither create the Secret holding vCenter credentials nor name the VDDK image, so both had to come from somewhere they cannot reach. Two CRDs in a new `forklift.cozystack.io` group, split by lifecycle. A VMImportSource is a long-lived connection -- type, endpoint, credentials, readiness -- and a VMImportTask is the one-shot operation that names machines and produces VMDisks and VMInstances. The outputs carry no owner reference back to the task, so deleting a finished import leaves the machines alone. Konveyor Forklift does the transfer underneath; the controller renders its objects, mirrors its verdicts, and hands each finished volume into a VMDisk without copying it. What a live vCenter migration forced out, and no amount of source reading would have: - A guest copied verbatim keeps the drivers it had under VMware and no virtio, so on a virtio disk it does not fail the import -- it succeeds and then does not boot. Imported disks go on SATA. - VDDK connects straight to the ESXi host at the address vCenter advertises, which is routinely unreachable, and on the first cluster collided with the Service CIDR. `spec.hosts` redirects per host. - Firmware must be carried across or a UEFI guest imports as BIOS and never boots (stacked on #3002). - Deleting a task mid-transfer orphaned its DataVolume; a finalizer now removes the engine's volumes and leaves the outputs. The console gains a Migration section: connections are editable, and the VM field is a picker built from a machine list the controller publishes, since the aggregated API cannot reach the inventory and should not hold a source's credentials to try. Two general mechanisms fall out of that -- an option source may take an argument, and one named in a CRD annotation may reference a sibling field. Design: cozystack/community#62.

What this PR does
Adds an optional
firmwareblock to thevm-instance(VMInstance) API so users can control VM boot firmware directly instead of relying solely on the OSinstanceProfile:firmware.bootloader—uefi(OVMF) orbios(SeaBIOS); empty inherits theinstanceProfiledefault (backward compatible).firmware.secureBoot— enable UEFI Secure Boot. KubeVirt requires SMM for Secure Boot, sodomain.features.smmis emitted automatically when set.firmware.efiPersistent— persist the EFI NVRAM across reboots, so in-guest changes to the EFI variable store (e.g. enrolling an updated Microsoft UEFI CA / Secure Boot keys) survive restarts.Rendered into
spec.template.spec.domain.firmwareof the generated KubeVirtVirtualMachine. The generatedvalues.schema.json, README, API types + deepcopy, and thevm-instance-rdApplicationDefinition were regenerated.Storage / live-migration note
efiPersistentuses a KubeVirt backend-storage PVC. On the default ReadWriteOnce storage that PVC pins the VM to its node, so a persistent-EFI VM cannot be live-migrated or drained — documented on the field, and sufficient for one-time in-guest tasks such as a Microsoft UEFI CA update (which only needs to survive reboots). Live-migration of a persistent-EFI VM would require an RWX-FilesystemvmStateStorageClassconfigured cluster-wide and is out of scope for this PR.Screenshots
No custom UI — the dashboard renders the new
firmwarefields automatically from the ApplicationDefinition schema.Release note
