virtui-manager 2.4.2

Terminal-based interface to manage virtual machines using libvirt

VirtUI Manager

A powerful, text-based Terminal User Interface (TUI) application for managing QEMU/KVM virtual machines using the libvirt Python API.

Why VirtUI Manager?

Managing virtual machines in a terminal environment has never been easier or more powerful. VirtUI Manager bridges the gap between the simplicity of command-line tools and the rich functionality of GUI-based solutions, offering the best of both worlds for virtualization administrators.

The Problem with Traditional Tools

• Virt-manager requires X11 forwarding, which is slow, resource-intensive, and often impossible in remote environments
• GUI-based solutions are heavy with X dependencies, making them unsuitable for headless servers or low-bandwidth connections
• Command-line tools lack the intuitive interface needed for complex VM management tasks
• Cockpit Machine is feature incomplete, and needs a lot of depencies. It is not multi hypervisor oriented
• Complex Deployment as there is nothing to manage easily auto-installation of Virtual Machine with registration process and auto installation

Why VirtUI Manager is Different

VirtUI Manager solves these challenges with:

• Lightweight Terminal Interface: No X11 dependencies, works perfectly over SSH
• Remote Management: Efficient low-bandwidth control of remote libvirt servers
• Rich Feature Set: Advanced VM management capabilities in a simple, intuitive interface
• Multi-server Support: Manage VMs across multiple libvirt servers from a single interface
• Performance Optimized: Built-in caching reduces libvirt calls and improves responsiveness (include a tracking resources call tool)
• Libvirt Event handler: Only get update on event from libvirt
• Migration Support: Live and offline VM migration capabilities and custom migration
• Bulk Operations: Execute commands across multiple VMs at once (including configuration)
• Web Console Access: Integrated VNC support with novnc over ssh tunnel for remote server
• CMD line interface: improved command line to manage VMs: multi hypervisors, VMs selection, clone operation, bulk command, etc...
• Auto installtion: Support auto installation for Debian, Ubuntu, Fedora, Archlinux (WIP), OpenSUSE and SLES (with SCC registration)

Requirements

• Recommended Minimal Terminal Size: 34x92. 34x128 is the recommended Size
• Remote Connection: SSH access to libvirt server (ssh-agent recommended)
• Python 3.7+
• libvirt with Python bindings
• Python Dependencies: see requirements.txt file
• Optional: virt-viewer, novnc, websockify for enhanced functionality
• Tmux: To edit file with pseudo terminal

Note about Libvirt API

As there is no simple way to get sound and network model using libvirt API, the user can provides a list in his own configuration file.

To get a list of model for a machine type you can use the qemu command line:

qemu-system-x86_64 -machine pc-q35-10.1 -audio  model=help
qemu-system-x86_64 -machine pc-q35-10.1 -net  model=help

Possible User config parameters:

• network_models: List of allowed network models (default: ['virtio', 'e1000', 'e1000e', 'rtl8139', 'ne2k_pci', 'pcnet'])
• sound_models: List of allowed sound models (default: ['none', 'ich6', 'ich9', 'ac97', 'sb16', 'usb'])
