What is Virt-Manager and how can it be used to manage a KVM virtualization environment?

In production environments, administrators need visibility and control over virtual machines to maintain performance and business continuity. Virt-Manager allows users to monitor running VMs, review real-time CPU and memory utilization, and manage hardware allocations through an intuitive interface . Rather than relying on complex shell commands, administrators can perform tasks using guided wizards and menus.

Creating a new virtual machine is straightforward. After preparing an ISO image, users can launch the “New Virtual Machine” wizard, select installation media, assign CPU and memory resources, configure storage size, and finalize deployment . The new VM then appears in the management list for ongoing monitoring.

Virt-Manager also enables editing existing VMs. Administrators can adjust CPU cores, memory allocation, storage settings, and other hardware configurations as needed. If a VM is no longer required, it can be deleted directly from the interface .

By offering graphical management, resource monitoring, VM lifecycle control, and configuration editing, Virt-Manager simplifies KVM administration. However, while it manages operations effectively, organizations should also consider backup and recovery strategies to protect virtual workloads.
