What is KVM + Cockpit?
KVM + Cockpit is a powerful virtualization and container management platform that combines the strengths of KVM (Kernel-based Virtual Machine) and Cockpit, a web-based management interface. This integrated solution enables users to create, manage, and monitor virtual machines (VMs) and containers, making it an ideal choice for organizations seeking to streamline their IT infrastructure.
Main Components
KVM + Cockpit consists of two primary components: KVM, a hypervisor that allows multiple VMs to run on a single physical host, and Cockpit, a web-based interface that simplifies VM and container management. This combination provides a robust and user-friendly platform for virtualization and containerization.
Key Features
Restore Points and Encryption
KVM + Cockpit offers robust restore points and encryption capabilities, ensuring that VMs and containers are protected against data loss and unauthorized access. With snapshotting and rollback features, users can easily revert to previous states in case of errors or issues.
Image Repositories and Immutable Storage
The platform provides image repositories and immutable storage, allowing users to store and manage VM and container images efficiently. This feature ensures that images are tamper-proof and can be easily rolled back in case of issues.
VM Snapshots and Clustering
KVM + Cockpit enables users to create snapshots of VMs, making it easier to manage and revert to previous states. The platform also supports clustering, allowing multiple hosts to work together as a single system, providing high availability and scalability.
