Almost exactly two years ago, I released the first tutorial for building 
an HA platform for KVM VMs. In that time, I have learned a lot, created 
some tools to simplify management and refined the design to handle 
corner-cases seen in the field.

Today, the culmination of that learning is summed up in the "2nd 
Edition" of that tutorial, now called "AN!Cluster Tutorial 2".


These HA KVM platforms have been in production for over two years now in 
facilities all over the world; Universities, municipal governments, 
corporate DCs, manufacturing facilities, etc. I've gotten wonderful 
feedback from users and all that real-world experience has been 
integrated into this new tutorial.

As always, everything is 100% open source and free-as-in-beer!

The major changes are:

* SELinux and iptables are enabled and used.
* Numerous slight changes made to the OS and cluster stack configuration 
to provide better corner-case fault handling.

* Architecture refinements;
** Redundant PSUs, UPSes and fence methods emphasized.
** Monitoring multiple UPSes added via modified apcupsd
** Detailed monitoring of LSI-based RAID controllers and drives
** Discussion on hardware considerations for VM performance based on 
anticipated work loads

* Naming convention changes to support the new AN!CDB dashboard[1]
** New alert system covered with fault and notable event alerting

* Wider array of guest OSes are covered;
** Windows 7
** Windows 8
** Windows 2008 R2
** Windows 2012
** Solaris 11
** FreeBSD 9
** RHEL 6
** SLES 11

Beyond that, the formatting of the tutorial itself has been slightly 
modified. I do think it is the easiest to follow tutorial I have yet 
been able to produce. I am very proud of this one! :D

As always, feedback is always very much appreciated. Everything from 
typos/grammar mistakes, functional problems or anything else is very 
valuable. I take all the feedback I get and use it to helping make the 
tutorials better.


Digimer, who now can now start the next tutorial in earnest!
