1.The processor does not support VT-x,or you can use VMware，Only in this   
  case,Performance does not like VT-x processors have so kind of good。      
  Intel® Virtualization Technology (Intel® VT) 
2.For example in VMware Workstation,The options can be seen in the processor，You can 
  choose a variety of analog。
  
3.the processor D525 does not support VT-X,Of course, no way to use Hyper-V，but can 
  still use VMware， but efficiency will be reduced。
