# Cluster Setting Scopes with Cluster Virtualization enabled

> [!NOTE]
>
> **This feature is in [preview](https://docs.cockroachlabs.com/docs/releases/cockroachdb-feature-availability.md)** and subject to change. To share feedback and/or issues, contact [Support](https://support.cockroachlabs.com).

Refer to the [Cluster Virtualization Overview](https://docs.cockroachlabs.com/docs/stable/cluster-virtualization-overview.md#known-limitations) for further detail.
When [cluster virtualization](https://docs.cockroachlabs.com/docs/stable/cluster-virtualization-overview.md) is enabled, each cluster setting has a scope, which may be a virtual cluster or the system virtual cluster. This page categorizes each public cluster setting by scope. For descriptions and details about each public cluster setting, refer to [Cluster Settings](https://docs.cockroachlabs.com/docs/stable/cluster-settings.md).

* When a cluster setting is scoped to a virtual cluster, it affects only a virtual cluster and not the system virtual cluster. To configure a cluster setting that is scoped to a virtual cluster, you must have the `admin` role on it, and you must connect to it before configuring the setting. The majority of cluster settings are scoped to a virtual cluster and are visible only when connected to it.
* When a cluster setting is scoped to the system virtual cluster, it affects the entire CockroachDB cluster. To configure a cluster setting that is scoped to the system virtual cluster, you must have the `admin` role on the system virtual cluster, and you must connect to the system virtual cluster before configuring the setting. For example, the cluster setting `admission.disk_bandwidth_tokens.elastic.enabled` is scoped to the system virtual cluster.
* When a cluster setting is system-visible, it can be set only from the system virtual cluster but can be queried from any virtual cluster. For example, a virtual cluster can query a system-visible cluster setting's value, such as `storage.max_sync_duration`, to help adapt to the CockroachDB cluster's configuration.
