title: Not valid kernel header path during vmware tools installation
body: <p>During the vmware tools instalation on a CentOS 7 MV (running on ESXi 5.5, tools version VMwareTools-8.6.5-621624) I have the next problem:</p>
  
  <pre><code>Searching for a valid kernel header path...
  The path "" is not a valid path to the 3.10.0-327.4.5.el7.x86_64 kernel
  headers.
  Would you like to change it? [yes]
  </code></pre>
  
  <p>I know that this problems is common. Normaly I solve it executing:</p>
  
  <pre><code>yum install kernel-headers
  yum install kernel-devel
  
  export kernel_headers=`ls -hd /usr/src/kernels/3*`
  
  sudo ln -s ${kernel_headers}/include/generated/uapi/linux/version.h ${kernel_headers}/include/linux/version.h
  </code></pre>
  
  <p>But this time, the error persist. The target MV is a critical mail server, and I can't reboot it. Any ideas?  </p>
  
  <p>Thank you very much.</p>
