title: How do i know my CPU supports Docker?
body: <p>What are now Docker cpu requirements for running in Linux, say, Ubuntu and Windows?</p>
  
  <p>Is VT-x/AMD-v is enough or VT-d/AMD-Vi is required too?</p>
  
  <p>Does it require MMU virtualization (Intel's Extended Page Tables (EPT) and Unrestricted Mode, and AMD's Nested Page Tables (NPT) and Rapid Virtualization Indexing (RVI)) like Hyper-V?</p>
  
  <p>Would Xeons with VT-x like 53xx, 54xx run both 32-bit and 64-bit docker images, or just 32-bit or none of them in say, Ubuntu?</p>
  
  <p>May be there is some tool to check for compatibility?</p>
