kvm virtualization in RHEL 5.4 Beta, howto

[ESGLinux]

Hi all,
I have installed the RHEL 5.4  Beta (see the press
http://press.redhat.com/2009/07/02/red-hat-enterprise-linux-5-4-beta-now-available/?sc_cid=70160000000Hv6dAAC
)

and I want to test KVM virtualization, but I don´t know how to test because
I´m totall newbie to this kind of virtualization.

I have installed the KVM group from pirut, but I dont see how to test it.

someone knows a good KVM-howto and the utilities that comes with RHEL 5.4
Beta for manage it?

Thanks all.
