What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) + Cockpit is a powerful virtualization and container management solution that enables users to deploy, manage, and monitor virtual machines (VMs) and containers on a single platform. This combination of KVM and Cockpit provides a robust and scalable infrastructure for enterprise operations, allowing administrators to efficiently manage resources, ensure high availability, and reduce mean time to recovery (MTTR).
Main Components
The KVM + Cockpit solution consists of two primary components:
- KVM: A kernel-based virtual machine that provides hardware virtualization for Linux on x86 hardware.
- Cockpit: A web-based interface for managing and monitoring KVM virtual machines, containers, and system resources.
