How to set-up multi node WildFly cluster in same machine?

How can i set-up

multiple nodes of WildFly in a single machine in Clustered mode ?

Should i create multiple Standalone nodes or multiple Domain nodes if I want to create all these multiple nodes in my 1 machine ?

Reason i want to have all nodes in 1 machine is because currently I am learning & validating few of it's capabilities.

Note: I referred to this http://middlewaremagic.com/jboss/?p=1952 but, i keep getting the following error

ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC000001: Failed to start service jboss.network.public: org.jboss.msc.service.StartException in service jboss.network.public: JBAS015810: failed to resolve interface public

Updated understanding on Standalone vs Domain: The HA or Failover feature provided by the multiple nodes in a cluster is the same between Standalone or Domain mode. The difference is that, in Domain mode, it allows the admins to manage/deploy all the nodes via a single (domain controler) node's Admin Console. This URL has a good explanation on it

Ref: https://docs.jboss.org/author/display/WFLY8/Admin+Guide#AdminGuide-

Update: As of now for learning purpose, i have configured to run multiple nodes in my machine using Domain mode blog.arungupta.me/wildfly-8-clustering-and-session-failover

Try to execute two or more instances on the same machine using a HA profile, choose the standalone-ha.xml. For example, on the same machine:

%WILDFLY_HOME_1%/standalone.bat -c standalone-ha.xml -Djboss.node.name=srv1;

and 

%WILDFLY_HOME_2%/standalone.bat -c standalone-ha.xml -Djboss.node.name=srv2 -Djboss.socket.binding.port-offset=100

and you'll have a cluster of two nodes on the same machine, the first one bound to port 8080 and the second one bound to port 8180. There is no need configuring a domain to have a cluster.
