KVM-35 is now available through the CentOS Extras repository for CentOS 5. To use it, install the kmod-kvm package for your kernel, and reboot your system (or restart udev) to make sure that the /dev/kvm device node gets correct permissions. At boot time, the kvm-amd or kvm-intel module will be loaded, based on the CPU extensions that were found in /proc/cpuinfo. Users that should be able to use KVM should be added to the kvm group. After that, virtual machines can be created through the qemu-kvm command, which is based on QEMU and follows the QEMU syntax.
