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