KubeVirt Update: v1.7.0 -> v1.9.1

This PR was automatically created by the KubeVirt update workflow.

Automated Changes

• Updated Chart.yaml appVersion to v1.9.1
• Updated operator image tag to v1.9.1
• Updated version references in README
• Regenerated documentation

Note: Chart version (0.x.y) is NOT automatically updated - it follows independent semantic versioning.

Manual Review Required

BEFORE MERGING, you MUST complete these steps:

1. Review Release Notes

• Read v1.9.1 Release Notes
• Identify breaking changes
• Note new features
• Check deprecations

2. Update Feature Gates

• Check if any Beta features became GA -> Remove from featureGates list
• Check for new Alpha/Beta features -> Add to comments in values.yaml
• Remove deprecated features from values.yaml

How to check:

# Search release notes for "feature gate" mentions
# Look for: "X is now GA", "new feature Y", "deprecated Z"

3. Update Configuration

• Check for renamed config options (e.g. bandwidthPerGiB -> bandwidthPerMigration)
• Update default values if recommended in release notes
• Verify GPU passthrough settings still compatible

4. Test Locally

# Lint
helm lint charts/kubevirt

# Template validation
helm template kubevirt charts/kubevirt --validate

# Dry-run
helm install kubevirt charts/kubevirt \\
  -f charts/kubevirt/ci/ci-values.yaml \\
  --dry-run --debug

# Install in test cluster (recommended)
helm install kubevirt charts/kubevirt \\
  -f charts/kubevirt/ci/ci-values.yaml \\
  --namespace kubevirt --create-namespace

# Run tests
helm test kubevirt -n kubevirt

5. Bump Chart Version

• Decide if this is a patch (0.x.y+1), minor (0.x+1.0), or major change
• Update Chart.yaml version field manually
• Update artifacthub.io/changes annotation with changelog

6. Update Documentation

• Update README.md.gotmpl with new features/changes
• Run helm-docs --chart-search-root=charts
• Commit documentation changes

7. Verify Templates

• Check if new KubeVirt components were added (DaemonSets, Services, etc.)
• Download and compare official manifests if unsure:

  curl -sL https://github.com/kubevirt/kubevirt/releases/download/v1.9.1/kubevirt-operator.yaml > /tmp/operator.yaml
  # Compare with templates/operator/

Notable changes

• [PR #19345][kubevirt-bot] Fixed a bug where a VM with RunStrategyRerunOnFailure incorrectly showed WaitingForVolumeBinding status after being manually stopped when its PVC was unbound.
• [PR #19346][kubevirt-bot] When Windows guest crashes and VM has a hyperv panic device configured, kubevirt no longer immediately terminates the VM and allows Windows to finish its default memory dump process and reboot. The actual behavior is guest-side configurable.
• [PR #19270][kubevirt-bot] BugFix: blockresize spam when doing I/O for filesystem volumes
• [PR #19122][michalskrivanek] Libvirt updated to 11.10.0-19.el9
• [PR #18833][dasionov] Bug fix: Prevent guest OS from ejecting critical PCI devices (disks, memory balloon, RNG, watchdog) via hotplug mechanisms like the Windows "Safely Remove Hardware" tray menu. PCI root ports hosting non-NIC devices are now marked as non-hotpluggable, while NIC ports and empty ports reserved for future hotplug remain available.
• [PR #19135][kubevirt-bot] Vera Rubin GPU (10de:3041) is now recognised as a Grace GPU, enabling GraceIOVirtualization for VMs with a passthrough Vera Rubin GPU.
• [PR #19055][dankenigsberg] deploy non-executable /var/lib/kubelet/seccomp/kubevirt/kubevirt.json
• [PR #19088][kubevirt-bot] BugFix: Prevent duplicate attachment pods when both utility volumes and hotplug volumes are used in a single VM
• [PR #18930][kubevirt-bot] Memory overcommit is now ignored for VMIs with hugepages
• [PR #19003][enp0s3] Bugfix: handle stale socket connections
• [PR #18933][kubevirt-bot] Updated virt-template to v0.2.3
• [PR #18931][kubevirt-bot] Fix PCI passthrough regression on kernels without CONFIG_VFIO_DEVICE_CDEV support. VMs with GPU/PCI host devices now correctly fall back to legacy VFIO group interface when IOMMUFD cdev is unavailable.
• [PR #18440][kubevirt-bot] Bugfix: Fix VM restore when backend storage is not snapshottable
• [PR #18869][sradco] Add mandatory namespace label, cluster-scoped, to OrphanedVirtualMachineInstances and VirtLauncherPodsStuckFailed alerts
• [PR #18864][kubevirt-bot] Bug fix: "virtctl evacuate-cancel" now works
• [PR #18583][kubevirt-bot] Fix CallNodeHooks to evaluate plugin-level Spec.Condition, ensuring consistent behavior between domain hooks and node hooks.
• [PR #18690][kubevirt-bot] BugFix: Online expansion scales poorly with many volumes
• [PR #18744][kubevirt-bot] Backend storage PVC size is increased by 1Gi for VMs with CBT enabled.
• [PR #18663][kubevirt-bot] Bug fix: During live migration, domain stats collection no longer blocks on the libvirt job lock for up to 30 seconds. The NOWAIT flag is used to skip locked domains instead of waiting, avoiding lock contention and disruptive error logs.

WARNING: DO NOT merge without completing the manual checklist above!

The most critical step is updating Feature Gates - GA features MUST be removed from the featureGates list.
