What is KVM + Cockpit?

KVM (Kernel-based Virtual Machine) is a virtualization infrastructure for the Linux kernel that turns it into a hypervisor. It 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 provides a user-friendly way to manage and monitor KVM virtual machines. Together, KVM + Cockpit provide a powerful and flexible virtualization solution for Linux environments.
