title: kubadm init error CPUs 1 is less than required 2
body: <p>Can anybody help me with this error. I have been following different links to install Kubernetes in centos 7 and I keep getting this error when i run the kubadm init command.  </p>
  
  <pre><code>[ERROR NumCPU]: the number of available CPUs 1 is less than the required 2               
  </code></pre>
  
  <p>Im not really sure what this means. I put the slave nodes IP in /etc/hosts/ file. Am I supposed to do something else. maybe add the node to a config file??? These are the links and steps I followed. </p>
