KVM (Kernel-based Virtual Machine) is a virtualization technology that allows you to run multiple operating systems, including multiple instances of the same operating system, concurrently on the same physical computer and it supports all major operating systems including Linux and Windows.
Install KVM Packages
Install KVM packages using your distro specific package management tool (for example, yum on RedHat and CentOS).
# yum install kvm
Once you install the main kvm package, install the following KVM related packages that will help you to manage the VMs on your system.
# yum install qemu-kvm python-virtinst libvirt libvirt-python virt-manager libguestfs-tools
The following are the KVM related packages that are installed on my machine. The version number on your system might vary slightly.
# rpm -qa | egrep "virt|kvm|qemu"
python-virtinst-0.600.0-18.el6.noarch
qemu-img-0.12.1.2-2.415.el6.x86_64
libvirt-0.10.2-29.el6.x86_64
virt-viewer-0.5.6-8.el6.x86_64
qemu-kvm-0.12.1.2-2.415.el6.x86_64
libvirt-python-0.10.2-29.el6.x86_64
virt-manager-0.9.0-19.el6.x86_64
virt-top-1.0.4-3.15.el6.x86_64
libvirt-client-0.10.2-29.el6.x86_64
gpxe-roms-qemu-0.9.7-6.10.el6.noarch
virt-what-1.11-1.2.el6.x86_64
After the packages are installed, it is recommended to reboot your machine to load all the KVM and libvirt modules, even though you can reload it using modprobe command.
