Installing KVM on RHEL6 is quite a simple process when having a yum repository. The main package is the kvm package (hypervisor). # yum install kvm To manage the vm’s you’ll need a tool called virt. # yum install virt-manager libvirt libvirt-python python-virtinst libvirt-client xorg-x11-xauth
List all virtual systems: #virsh list Start/Stop virtual os: #virsh start virtosname #virsh shutdown virtosname #virsh destroy virtosname (like a power off) Access a virtual console: # virsh console virtosname Autostart virsh server: # virsh autostart virtosname
