What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) and Cockpit are two powerful tools that, when combined, provide a robust and secure 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 KVM virtual machines and containers. Together, KVM + Cockpit offer a comprehensive platform for deploying and managing virtualized environments.
Main Features of KVM + Cockpit
The combination of KVM and Cockpit provides several key features that make it an attractive solution for virtualization and containerization needs. Some of the main features include:
- Secure repositories: KVM + Cockpit allows users to create and manage secure repositories for their virtual machines and containers, ensuring that sensitive data is protected.
- Snapshot and restore workflow: The platform provides a robust snapshot and restore workflow, enabling users to easily capture and revert to previous states of their virtual machines and containers.
- Encryption: KVM + Cockpit supports encryption, providing an additional layer of security for virtual machines and containers.
