What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) is an open-source virtualization technology that allows 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 virtual machines, containers, and other system resources. When combined, KVM + Cockpit provide a powerful and user-friendly platform for virtualization and containerization.
Main Components
The KVM + Cockpit platform consists of two main components: the KVM hypervisor and the Cockpit management interface.
- KVM Hypervisor: The KVM hypervisor is responsible for managing the virtual machines and allocating system resources such as CPU, memory, and storage.
- Cockpit Management Interface: The Cockpit management interface provides a user-friendly web-based interface for managing virtual machines, containers, and other system resources.
Key Features
Virtualization and Containerization
KVM + Cockpit support both virtualization and containerization, allowing users to run multiple virtual machines and containers on a single physical host.
Virtualization
KVM supports full virtualization, which means that each virtual machine runs its own operating system and has its own virtual hardware.
Containerization
Cockpit supports containerization using Docker, which allows users to run multiple containers on a single host operating system.
Snapshot and Restore Workflow
KVM + Cockpit provide a snapshot and restore workflow that allows users to easily create and manage snapshots of their virtual machines and containers.
Snapshot Creation
Users can create snapshots of their virtual machines and containers at any time, which allows them to easily revert back to a previous state in case something goes wrong.
Snapshot Management
The snapshot management feature allows users to easily manage their snapshots, including deleting and merging snapshots.
Repositories and Rollback
KVM + Cockpit provide a repository feature that allows users to easily manage their virtual machines and containers, including rolling back to a previous version.
Repository Management
Users can create and manage repositories for their virtual machines and containers, which allows them to easily track changes and roll back to a previous version.
Rollback Feature
The rollback feature allows users to easily revert back to a previous version of their virtual machine or container in case something goes wrong.
