== Deprecated features

The `HotplugVolume` feature gate is deprecated::

The `HotplugVolume` feature gate, which allows you to add storage without restarting your VM, is deprecated and will be removed in a future release. This feature gate will be replaced by `DeclarativeHotplugVolumes`.
+
[NOTE]
====
`DeclarativeHotplugVolumes` does not support hot plugging ephemeral volumes. Ephemeral volumes are hot plugged to a VMI and do not persist in the owner VM. Existing ephemeral volumes that are hot plugged are automatically detached after you switch to the `DeclarativeHotplugVolumes` feature gate.
