title: XenServer vs VMware Infrastructure
body: <p>Does anyone have experience of comparing Xen Server 5 and VMWare Infrastructure 3. I'm planning a virtualization project and looking at the Enterprise edition of both. They both seem to offer very comparable functionality so am unsure which is the best option.</p>
  
  <p>Does anyone know any good sites or articles that compares these products?</p>
  
  <p>Alternatively can anyone answer any of the following questions:</p>
  
  <p>1) Is there any significant performance differences?<br>
  2) Does either package have any security risks or vulnerabilities.<br>
  3) The Xen Server SDK seems easier to understand than VMware SDK. Anyone have any experience of both and can compare? Is either SDK lacking in any respect?<br>
  4) Any comments on the client side tools? To me they both seem pretty equivalent, but is there anything lacking from either one?<br></p>
  
  <p>Or any other general comments and observations would be appreciated.</p>
  
  <p>Thanks,</p>
