What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) and Cockpit are two powerful tools that, when combined, provide a comprehensive virtualization and containerization solution. KVM is a virtualization infrastructure for the Linux kernel, allowing users to run multiple virtual machines on a single physical host. Cockpit, on the other hand, is a web-based management interface that simplifies the management of Linux servers, including those running KVM.
Main Benefits of KVM + Cockpit
The combination of KVM and Cockpit offers several benefits, including improved manageability, scalability, and security. With KVM, users can create and manage multiple virtual machines, each with its own operating system and resources. Cockpit provides a user-friendly interface for managing these virtual machines, as well as the underlying host system.
