    initial v1  
    11For clarification: What you'll want to do is set vCPU to 1 and boot Linux and run the script.  Note the good latency numbers.  Now power off, set vCPU to 4, and run the script again.  The reported latency numbers are terrible.  If you have a cpu with 8 threads, you can try 8 vCPUs ... the script barely runs, nearly all the 1ms sleep calls are horribly long (as an extreme example).  Even 2 vCPUs is not nearly as good as 1 vCPU.

     3Also the same problem whether Win10 host or openSUSE TW host.  Same problem with openSUSE TW guest or Ubuntu 16/18 guest.
