Hello, do you know what is KVM and how to install it?

I researched little bit and pasting what i found:

- KVM is already included in new linux releases - operating systems. Check whether linux support KVM: modprobe -l | grep kvm
- KVM should reside in /lib/modules/linux-`uname -r` (but this folder does not exist on my CentOS 5 :-/)
- Activate KVM by: modprobe kvm; modprobe kvm_intel OR modprobe kvm; modprobe kvm_amd (I got: No such file or directory)
- KVM can be managed by several virtual machine tools most famous is Proxmox (free) and SolusVM (paid-$10/mo.)
