# Configure Host as Image Library

You need to configure at least one host with the image library role so that your PMO cloud can use that host to store and serve your VM images to create new virtual machines from.

As part of this process, you need to specify the location (the directory path) to store image content on the host. The default path is `/var/opt/pf9/imagelibrary/data`.

You can configure multiple hosts as image library hosts in PMO. We recommend doing this for a production environment to create a **highly available image catalog**.

{% hint style="info" %}
**IMPORTANT**

When you have multiple image library hosts, the image storage path on all image library hosts must be the same.
{% endhint %}

To configure image library settings for a host, follow the steps given below.

```
1. Log in to Clarity.

2. Click Infrastructure in the left panel.

3. Click the Hosts tab.

4. Select a host and click Configure Host seen above the list of hosts.

```
5. Click the Image Library tab.

6. Select the Yes check box for Make host an Image Library.

7. Specify the directory path to store the image content.

8. Select the IP address (access point) for Image Library access.

9. Select the Yes check box if you want to make the host a public Glance endpoint.

10. Click Update Image Library details.
```

The host is ready to be used as a Glance image library.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.platform9.com/managed-openstack/infrastructure/host-management/infrastructure-configure-host-as-image-library.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
