What is KVM + Cockpit?

KVM (Kernel-based Virtual Machine) is a popular open-source virtualization platform that allows users to run multiple virtual machines on a single physical host. Cockpit, on the other hand, is a web-based management interface that simplifies the process of managing and monitoring KVM virtual machines. When combined, KVM + Cockpit provides a powerful and user-friendly solution for virtualization and container management.
