+          tip: "How the host caches disk I/O. \"None\" (host cache disabled) is best for high-throughput guests on block storage; \"WriteBack\" favours performance; \"WriteThrough\" favours durability."

+        dedicatedIOThread:
+          label: Dedicated I/O Thread
+          tip: Allocate an exclusive libvirt I/O thread to this disk instead of sharing one. Useful for disks with heavy I/O. Enabling this on any disk turns on the VM's I/O threads policy.
+        busTip: High-performance features work best on the virtio bus.
+      diskPerformance:

+        blockMultiQueue:
+          label: Virtio Block Multi-Queue
+          tip: Map disk I/O to multiple queues so it is processed across multiple CPUs. Applies to virtio disks and requires a fixed CPU allocation (Harvester always sets one).
+          noVirtioTip: Add at least one disk on the virtio bus to enable Block Multi-Queue.
+        ioThreadsPolicy:
+          label: I/O Threads Policy
+          tip: "How libvirt allocates I/O threads. \"Shared\" uses one thread for all disks; \"Auto\" pools threads round-robin (up to ~2x vCPUs); \"Supplemental Pool\" lets you pick a fixed thread count and adds matching CPUs to the pod."
+          default: "Disabled (default)"
+          shared: Shared
+          auto: Auto
+          supplementalPool: Supplemental Pool
+          autoEnabledTip: A disk requests a dedicated I/O thread, so the policy is enabled (defaults to "Shared").
+        ioThreadCount:
+          label: I/O Thread Count
+          tip: Number of I/O threads for the supplemental pool. 4-8 is a common range depending on workload.
