title: How to get rid of "REMOTE HOST IDENTIFICATION HAS CHANGED" message
body: <p>I have several virtual machines installed on my computer, to which I connect via ssh:</p>
  
  <pre><code>ssh vm1@localhost
  </code></pre>
  
  <p>or</p>
  
  <pre><code>ssh vm2@localhost
  </code></pre>
  
  <p>So every time I connect to different vm I need to edit my <code>~/.ssh/known_hosts</code> file in order to get rid of: “<code>WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!</code>” message.</p>
  
  <p>Is there any way to trust automatically all VMs on localhost?</p>
