About Virtual Machine Manager
virt-manager manages virtual machines through libvirt. In practice that means QEMU and KVM, but Xen and libvirt LXC containers work too. It creates machines, edits their hardware, opens a console over SPICE or VNC, takes snapshots and handles storage pools and virtual networks.
It comes with command line tools that do the same jobs without a desktop: virt-install to create machines, virt-clone to duplicate them, and virt-xml to edit their definitions. Because everything goes through libvirt, a machine created here runs on any other libvirt host.
Strengths
- The standard interface for KVM, so guides and answers are everywhere
- Command line tools for creating and editing machines without a desktop
- Manages remote libvirt hosts over SSH from the same window
- Machines are portable to any other libvirt host
Limitations
- Linux only
- The interface is functional and has barely changed in years
- Releases are infrequent; 5.1.0 dates from August 2025
- Storage pools and virtual networks assume some libvirt knowledge
