Overview

virt-manager is a desktop application for managing virtual machines through libvirt, primarily KVM but also Xen and LXC containers. It shows running domains with live performance and resource utilisation statistics, and wizards handle domain creation plus changes to resource allocation and virtual hardware. An embedded VNC and SPICE client gives a graphical console to the guest.

Best for: Administrators managing KVM, Xen or LXC guests from a Linux desktop through libvirt.
Pricing: No pricing is shown on the page; it offers distribution packages, a source release and a public git repository.
Runs on: WindowsLinux
