# virtualization

Use the `virtualization` InSpec audit resource to test the virtualization platform on which the system is running.

## Syntax

An `virtualization` resource block declares the virtualization platform that should be tested:

    describe virtualization do
      its('system') { should MATCHER 'value' }
    end

where

* `('system')` is the name of the system information of the virtualization platform (e.g. docker, lxc, vbox, kvm, etc)
* `MATCHER` is a valid matcher for this resource
* `'value'` is the value to be tested

## Matchers

This InSpec audit resource has the following matchers:

### be

<%= partial "/shared/matcher_be" %>

### cmp

<%= partial "/shared/matcher_cmp" %>

### eq

<%= partial "/shared/matcher_eq" %>

### include

<%= partial "/shared/matcher_include" %>

### match

<%= partial "/shared/matcher_match" %>

## Examples

The following examples show how to use this InSpec audit resource.

### Test for Docker

    describe virtualization do
      its('system') { should eq 'docker' }
    end

### Test for VirtualBox

    describe virtualization do
      its('system') { should eq 'vbox' }
      its('role') { should eq 'guest' }
    end

### Detect the virtualization platform

    if virtualization.system == 'vbox'
      describe package('name') do
        it { should be_installed }
      end
    end
