Hi Ahmed,

Thanks for your advice.

I succeeded installing cluster as VM of PC-1.  It is running and can be 
connected on browser remotely via Internet.  But I failed to get the node 
running as VM of PC-1, in the same PC.

I'll try installing a node as VM of PC-2 later.  If failure making the cloud to 
work I would stop testing cloud computing until solution discovered.

Running virtualization?  


Cloud computing is NOT a new technology, only the main frame and terminals on 
the service provider's server.  This is a technology of yesterday tracing back 
to Utility Computing, Grid Engine, etc, several years back. I tested the later 
at least 4~5 years ago. At that time they were run by universities sharing data.


I found following thread:-
The Enterprise Cloud: How to Build a Server Demo
http://www.youtube.com/watch?v=T6lvKnbws78&feature=mfu_in_order&playnext=1&videos=sIemMxnTfDk


Created by Terremark showing how to create a server on Web.

Previously I did it in another way creating several servers (nodes), Linux and 
Windows, on VirtualBox/KVM. Users have full access to the servers over Internet 
with the IP address and password provided, on command line and GUI (RDP).  


I think the concept is more or less the same.  I have following doubt :-

Can the user have full knowhow and experience on monitoring and configuring the 
server? If YES he/she would build the server themselves, not to down/buy a 
server.

I will be happy to see what new technology will be added to cloud computing in 
the not too distant future.

Hey Stephen,

Two get a "supported" installation, you'd need 2 PCs minimum.
PC-1 To act as cloud controller, cluster controller and storage (walrus, SC)
PC-2 To act as "node". You can later on add as many nodes as you want

I would be quite hesitant to install any of those as "VMs". There are 
hacks to install everything on one node, but they're just hacks
