# Integration with Chef/Ohai

If you're using Chef to provision your Parallels virtual machines or host systems running Parallels Desktop, you can check in the recipe that the type of system virtualization being used is virtualization from Parallels. To do this, use the node\['virtualization'] attribute. This attribute is set by [Ohai](https://github.com/chef/ohai) during the chef-client run.

{% hint style="info" %}
**Note:** The [Ohai](https://github.com/chef/ohai) version must be 8.6.0 or later.
{% endhint %}

You will see the following in the host system:

```
"virtualization": {
  "systems": {
    "parallels": "host"
  },
  "system": "parallels",
  "role": "host"
```

And the following in the guest system:

```
"virtualization": {
    "systems": {
      "parallels": "guest"
    },
    "system": "parallels",
    "role": "guest"
 
}
```

## 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://docs.parallels.com/landing/parallels-desktop-developers-guide/integrations-and-plugins/integration-with-chef-ohai.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.
