</span>I have no thoughts or concerns about performance, that's a question for<br>
you and your users. I only care about properly built HA. :)<br>
<br>
If your goal is to build an HA VM platform, and setup your HA<br>
applications in VMs, you could try following the tutorial as it is (cman<br>
+ rgmanager + drbd). It may not be the most up-to-date set of<br>
applications, but it's very well field tested.<br>
