What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) is an open-source virtualization platform that allows users to run multiple virtual machines on a single physical host. Cockpit is a web-based interface that simplifies the management of KVM virtual machines, providing a user-friendly dashboard for monitoring, configuring, and troubleshooting. Together, KVM + Cockpit offer a powerful and efficient solution for virtualization and containerization.
Main Benefits
The combination of KVM and Cockpit provides several benefits, including improved performance, enhanced security, and simplified management. With KVM, users can create and manage multiple virtual machines, each with its own operating system and resources. Cockpit adds a user-friendly interface to this functionality, making it easier to manage and monitor virtual machines.
