I've modified the tests to only skip quiesce for cirros VMs but not alpine/fedora. |
WalkthroughThe backup helper now accepts annotations and applies them to Velero Backup metadata. KubeVirt datamover tests add quiesce control, stronger backup polling and cleanup, live CBT restore coverage, conflict-retried decoy updates, and exclusive PVC payload verification. ChangesKubeVirt backup and restore tests
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The PR adds skip-quiesce annotations to KubeVirt datamover backup tests. A failed VM halt can still cause a restart assertion to fail when the VM is already running, creating a bounded test-reliability risk that should be addressed or explicitly accepted before merge.

Full details: Description checkExplanation The description explains why the change was made and identifies the affected Cirros test VMs. The required testing section contains only the template comment and provides no commands or verification steps.

It does not add or modify any Ginkgo It, Describe, Context, When, Entry, or DescribeTable title.

@coderabbitai open issue in for tracking improvements in migtools/kubevirt-datamover-controller repo itself: Better design is to have kdm-controller check on VMI.Status.Conditions[AgentConnected]==True by default — real detection, but allow user override.. |

## Summary
Improve quiesce behavior in the KubeVirt datamover controller.
The controller must detect guest-agent availability from the VMI status condition by default. It must use \`VMI.Status.Conditions[AgentConnected] == True\` to determine whether quiesce is available.
Users must be able to explicitly override the default behavior.
## Rationale
The controller can make a correct quiesce decision from the VMI status instead of requiring workload-specific test annotations. This reduces configuration for VMs that do not have a connected guest agent, such as Cirros test VMs.
## Affected area
- KubeVirt datamover controller backup and quiesce decision logic.
- Configuration or annotation handling for an explicit user override.
## Required changes
1. Before the controller requests quiesce, inspect \`VMI.Status.Conditions\` for \`AgentConnected == True\`.
2. When \`AgentConnected\` is not true, skip quiesce by default.
3. Provide an explicit user override that can force or disable the default quiesce decision.
4. Document the override behavior and its precedence over automatic detection.
5. Add unit and integration coverage for VMs with and without an agent-connected condition, and for each override mode.
## Acceptance criteria
- A VMI with \`AgentConnected == True\` uses quiesce by default.
- A VMI without \`AgentConnected == True\` skips quiesce by default.
- An explicit user override takes precedence over automatic detection.
- Tests cover automatic detection and user override behavior.
- Documentation describes the default and override behavior.

1634-1635: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winMake the restart tolerant when the halt failed.
EnsureVmHaltedForExclusivePVCAccessreturns an error in two different states:StopVmfailed (the VM is still running), orStopVmsucceeded but the virt-launcher pod never went away. The comment covers only the second state. In the first state the VM is still running, soStartVmcalls the start subresource on a running VM, which the KubeVirt API rejects. The hardgomega.Expectthen fails the spec, which defeats the intended skip path at Line 1636.Restart only when the halt succeeded, or log the start error instead of asserting on it when
haltErr != nil.🐛 Proposed fix
- err = v.StartVm(alpineNamespace, alpineVMName) - gomega.Expect(err).ToNot(gomega.HaveOccurred(), "failed to restart VM %s/%s after checksum", alpineNamespace, alpineVMName) + // StopVm is always attempted, so restart unconditionally -- but a + // failed halt can leave the VM already running, in which case the + // start subresource legitimately errors and must not fail the spec. + if startErr := v.StartVm(alpineNamespace, alpineVMName); startErr != nil { + if haltErr == nil { + gomega.Expect(startErr).ToNot(gomega.HaveOccurred(), "failed to restart VM %s/%s after checksum", alpineNamespace, alpineVMName) + } else { + log.Printf("WARNING: could not restart VM %s/%s after a failed halt: %v", alpineNamespace, alpineVMName, startErr) + } + }🤖 Prompt for AI Agents

Why the changes were made
This PR updates the kubevirt-dm tests to set the annotation "kubevirt-datamover.io/skip-quiesce=true" so that when the kubevirt-dm implements skipQuiesce, we will skip quiesce on the cirros test VMs that don't support it.
