What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) and Cockpit are two powerful tools that can be combined to create a robust virtualization and container management solution. KVM is a hypervisor that allows you to run multiple virtual machines (VMs) on a single physical host, while Cockpit is a web-based interface for managing and monitoring your infrastructure. By combining KVM and Cockpit, you can create a scalable and efficient solution for managing your virtual infrastructure.
