KVM Cloudmin install failure

I get the following error using the install script for Cloudmin KVM gpl on a standard fresh install of CentOS 6.2 minimum: No package kvm available. No package kvm-qemu-img available. No package qemu-kvm available. No package qemu-img available. No package qemu-kvm-tools available. No package kvm-tools available. No package kmod-kvm available.

As a result, the script ends with the following lines: Activating KVM kernel module .. FATAL: Module kvm_intel not found. FATAL: Module kvm_amd not found. .. kernel module did not load successfully

any ideas?
