Hii Ziv,

Could you please explain in more detail.  Whether Ubuntu Cloud is already a 
platform with a virtualizer, say KVM or VirtualBox, running on it.  It allows VM 
to be installed and running on it.  If my assumption is correct.  Ubuntu Cloud 
is command line operation without X.  I can't run Virtual Machine Manager (GUI) 
on it.  Then the installation of VM (node) must be on command line?  If I'm 
wrong please advise.  TIA

Whether to find a new PC installing Win7 as host and then installing VirtualBox 
on it.  In such configuration I can install both cluster and nodes on VirtualBox 
as VMs?  I'm now running Ubuntu as host with VirtualBox installed on it.  This 
change is only on the host.  Sorry I can't see the difference.  Pls advise.  
Thanks
