virt-manager uses the Python bindings provided by the libvirt project
(http://libvirt.org) to communicate with the Xen hypervisor. Libvirt provides
an API to interface with various hypervisors such as Xen, Qemu, and KVM in a
hypervisor independent way. So virt-manager can be used not only with the Xen
hypervisor, but also with these other virtualization technologies. It provides a great
way to manage your local Xen domains. The virt-install command line tool provided
by the virt-manager can be used for provisioning systems, and we will use this tool
when will examine the topic of provisioning Xen domains in Chapter 8.
