title: vmware virtualized intel vt-x/ept requires a preferred mode of Intel VT-x/ept reverting to automatic?
body: <p>Window System 7x64 SP1
  VM Workstation 11</p>
  
  <p>When virtualization engine preferred mode is explicitly enabled with <code>Intel VT-x or AMD-V</code>, the following message is displayed during boot of the VM:</p>
  
  <blockquote>

  </blockquote>
  
  <p>The Intel Processor Identification Utility (PIU) reports Virtualization technologies capabilities. In the BIOS, it does not have an option to explicitly enable VT-x.  </p>
  
  <p>Q: Does the PIU test indicate the VT-x is enabled implicitly in the BIOS  </p>
  
  <p>When booting with virtualization engine preferred mode is explicitly enabled with Automatic. The settings appear with both virtualize VT-x/EPT and CPU performance grayed out:</p>

  <p>Q: I am uncertain what this means?</p>
  
  <p>Q: Is there a way (a service, process, etc) to determine if Virtualization technologies are being enabled for the VM?</p>
