# Hyper-V environment is not visible in XMS despite installing the agent on the host

## Issue

> You cannot see your **Hyper-V** environment in **Xopero ONE Management Service** (**XMS**) even after installing the agent on the host.

***

## Resolution

Remember to use the appropriate installer to natively secure the **Hyper-V** host for external backup. This dedicated installer can be downloaded from the [**XMS**](#user-content-fn-1)[^1] in **Virtual Machines** > **Hyper-V** tab using the **(+) Add new** button.

{% hint style="danger" %}
If the **Hyper-V** host was added as a regular agent (with endpoint or server license), go to the **Devices** tab, select the device, and choose **Delete** from the top menu (<mark style="color:$danger;">**without deleting data**</mark>). With the correct installer and a **Hyper-V** per socket license, the license will be assigned automatically.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://helpcenter.xopero.com/xopero-one-en/common-issues/virtual-machines/hyper-v/hyper-v-environment-is-not-visible-in-xms-despite-installing-the-agent-on-the-host.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
