What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) is a widely used virtualization solution for Linux systems, enabling users to run multiple operating systems 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. The combination of KVM + Cockpit provides a powerful and user-friendly platform for virtualization and container management.
