# Cluster Setting Scopes with Cluster Virtualization enabled

export const InternalLink = ({version, path = "", children, ...props}) => {

  **This feature is in <InternalLink path="cockroachdb-feature-availability">preview</InternalLink>** and subject to change. To share feedback and/or issues, contact [Support](https://support.cockroachlabs.com).
</Note>

Refer to the <InternalLink path="cluster-virtualization-overview#known-limitations">Cluster Virtualization Overview</InternalLink> for further detail.
When <InternalLink path="cluster-virtualization-overview">cluster virtualization</InternalLink> 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 <InternalLink path="cluster-settings">Cluster Settings</InternalLink>.

* 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.
