title: Oracle Virtual Server OEL vm fails to start - kernel panic on cpu identify
body: <p>I am in the process of following a guide to setup various oracle vm templates, so far I have installed OVS 2. 2 and got the OVM Manager working, imported the template for OEL5U5 and created a vm from it.. the problem comes when starting that vm.</p>
  
  <p>The log in the OVMM console shows the following;</p>
  
  <pre><code>Update VM Status - Running

  <p>clear as mud to me.<BR></p>
  
  <p>are there any other logs that will help me?<BR></p>
  
  <p>I have now deployed another vm from the same template and used the default vm settings rather than adding more memory etc - I get exactly the same error.</p>
