# Citrix Xen Hyper-V Discovery

ServiceNow Discovery uses the Citrix Xen Hyper-V pattern to find and map instances. Discover these resources by installing the pattern applications from the ServiceNow Store and add Citrix Xen Hyper-V to the Linux Server Pattern’s Extension Section.

Use the Xen \(XE\) and \(XL\) commands to discover Citrix Xen Hyper-V, its components, and respective attributes. Discover information regarding the Hyper-V Server, Associated Pools, VMs, Network and Storage and their relationships with new and existing CIs.

## Request apps on the Store

Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://www.servicenow.com/docs/r/store-release-notes/sn-store-release-notes.html).

## Prerequisites

-   **Verify the following applications are up to date**
    -   Discovery and Service Mapping Patterns
    -   CMDB CI Class Models
-   **Verify pool admin RBAC role**

    This role is required for SSH access to the Linux server hosting the hypervisor and for executing all the necessary commands to extract information from the hypervisor environment. For more information on RBAC role permissions or adding Citrix users to a domain and assigning roles, see the [Citrix documentation](https://docs.citrix.com/).

-   **Verify MID Server reachability**

    Verify MID Server has reachability to the target device.

-   **Create SSH credentials with access to the target Linux host**

    For more information, see [SSH credentials](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-security/r_SSHCredentialsForm.md)

-   **Create an extension section after the Linux Server pattern**

    Create an extension section after the Linux Server pattern and associate the **Citrix Xen HyperV** pattern to be triggered after the execution of the Linux Server discovery pattern. For more information on creating extension sections, see [Enhance patterns without modifying identification sections](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery-and-service-mapping-patterns/modify-pattern-using-extensions.md).
