Hi All,

I have RHEL 5, I want to implement Virtualization.  As you know there are two type full and para virtulization.  I don'nt know exactly the different between them.  But which one do you recommend to use. With my understanding para-virtulisation is better performance, but is it more difficult to configure and cupport.  I use it for web hosting, which on shall i go for

    use kvm
    it makes use of the hardware virtualization and is set to be the future of redhat's virtualization strategy

    I was confused to choose between full or para virtulization, now you mentioned kvm! what is the advantage of kvm over virtul, it is easy to configure and maintain, how about performance?
