What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) + Cockpit is a powerful combination of virtualization and containerization technologies that provides a secure, efficient, and easy-to-use platform for managing virtual machines and containers. KVM is a hypervisor that allows you to run multiple virtual machines on a single physical host, while Cockpit is a web-based management interface that simplifies the process of managing and monitoring your virtual infrastructure.
