desktop application for managing virtual machines

 The virt-manager application is a desktop user interface for managing virtual
 machines through libvirt. It primarily targets KVM VMs, but also manages Xen
 and LXC (Linux containers). It presents a summary view of running domains,
 their live performance & resource utilization statistics. Wizards enable the
 creation of new domains, and configuration & adjustment of a domain's resource
 allocation & virtual hardware. An embedded VNC and SPICE client viewer
 presents a full graphical console to the guest domain.
