As discussed in previous chapters of this book, virtualization is the ability to run multiple operating systems simultaneously on a single computer system. There are a number of ways to implement virtualization on Fedora. Options include (but are not limited to) VMWare, Xen, VirtualBox and KVM. In the preceding chapters we looked in detail at configuring and maintaining Xen based virtualization. In this and subsequent chapters we will look at KVM based virtualization hosted on a Fedora system.

The main virt-manager screen lists the current virtual machines running on the system. At this point there should only be one, the host system. By default the manager should be connected to the host. If it is not, connect to the host system by right clicking on the entry in the list and selecting ''Connect'' from the popup menu. The ''Status'' field for this VM should now change to ''Active'', and the ''New'' button at the bottom of the dialog should be enabled.

For information on administering a virtual system read [[Managing and Monitoring Fedora based KVM Guest Systems]].
