Marcelo Fukumoto 7976687a1e feat: align the storage performance options with the Rancher machine pool form (#1212)
* feat: align the storage performance options with the Rancher machine pool form

Show the storage performance profile on every volume instead of behind a
collapsible toggle, and move the VM-wide options to a plain Storage
Performance section in the Advanced Options tab. Put the Native I/O tip in
a live region so screen readers announce the cache mode change, use an
integer input for the I/O thread count, and use the same copy as the
Rancher form.

Skip the view-only backup row in the image and container volumes when it
has nothing to show, so it no longer adds an empty gap above the profile.

* fix: announce the storage performance warnings and name the virtio requirement

- Put the bus tip and the Filesystem warning in an always-rendered status
  region. They appear above the field being changed, so screen readers need
  them announced.
- Say in the bus tip that a dedicated I/O thread needs the virtio bus, because
  KubeVirt rejects it on any other bus.
- Mark I/O Thread Count as required while editing, like the Rancher form.

* fix: state only the dedicated I/O thread requirement in the bus tip

Neither the Harvester docs nor KubeVirt tie cache mode or I/O mode to the bus,
so stop saying that those options work best on virtio.

Alejandro BonillaandClaude 528255dea4 feat: expose KubeVirt high-performance storage features in VM and Volume UI (#1133)
* feat: expose KubeVirt high-performance storage features in VM and Volume UI

Adds UI to configure KubeVirt high-performance disk/storage settings that
were previously only reachable via VMBuilder/Terraform:

- Per-volume "Storage Performance Options": a performance profile
  (Default / High Performance / Custom) exposing per-disk cache, io and
  dedicatedIOThread on all disk types (VM image/root, new, existing,
  container) and on the standalone Volume form.
- VM-wide "High Performance (I/O Threads and Multi-Queue)": blockMultiQueue
  and ioThreadsPolicy (+ supplemental-pool thread count), shown only in the
  VM section since these are domain-level and cannot be set per-PVC.
- Compatibility guardrails: io=native forces cache=none; cache=none on
  Filesystem volumeMode warns; blockMultiQueue requires a virtio disk.

* fix: address review feedback on high-performance storage UI

Resolves the Copilot review comments on #1133:

- Gate the whole feature behind a new `highPerformanceStorage` release
  feature flag (v1.9.0) so older supported clusters never render the
  controls or receive unsupported KubeVirt fields.
- Force Cache Mode to "none" whenever Native I/O is selected, including
  from the "Default" ('') cache value, and disable every non-"none" cache
  option (Default included) while Native is active. Previously the empty
  cache value slipped past the guardrail and produced an invalid combo.
- Clear an already-enabled blockMultiQueue when the last virtio disk is
  removed, so a disabled checkbox can no longer persist an invalid setting.
- Strip stale cache/io/dedicatedIOThread fields from the merged disk spec
  when a regenerated disk no longer requests them, so switching a disk back
  to "Default" (or unchecking Dedicated I/O Thread) while editing no longer
  silently preserves the previous values.
- Expose the disclosure toggle's state to assistive tech via aria-expanded
  and an expand/collapse aria-label.
- Add unit tests for the profile transitions and the Native/cache guardrails.

* fix: address second-round review on high-performance storage UI

Resolves the two Copilot findings on #1133 and votdev's UX feedback on
harvester/harvester#11550:

- Restore the disk's original bus when the performance profile goes back
  to "Default". The "High Performance" preset switches the bus to virtio,
  but leaving the preset only cleared cache/io/dedicatedIOThread, so a
  SATA/SCSI disk was silently left on virtio — a bus change that can make
  an existing guest unbootable. The pre-preset bus is now remembered and
  put back, unless the user picked a different bus themselves in the
  meantime.
- Pass the VM-wide performance values from the VM detail page to the
  shared Volume component. The mixin already parsed them via
  getInitConfig(), but the detail caller never forwarded them, so
  VMPerformanceOptions fell back to its prop defaults and hid itself in
  view mode — configured blockMultiQueue / ioThreadsPolicy settings were
  invisible. They are also refreshed in the value watcher so the panel
  does not go stale.
- Make the VM-wide "High Performance" panel expandable/collapsible,
  matching the per-volume "Storage Performance Options" disclosure. It
  stays collapsed unless the VM already has something configured, so the
  average user is not faced with specialist tuning controls by default.
- Fix the unit tests to use Vue Test Utils v2 mount options. They used
  the v1 top-level `mocks` key, which VTU 2.x ignores, so every case
  failed on mount. The repo has no jest config or test script, so this
  was not caught. Add coverage for the bus save/restore behaviour.
