What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) is an open-source virtualization platform that allows you to run multiple virtual machines on a single physical host. Cockpit, on the other hand, is a web-based management interface that provides a user-friendly way to manage and monitor your KVM infrastructure. By combining KVM and Cockpit, you can create a powerful and efficient virtualization solution that meets your organization’s needs.
Main Benefits of KVM + Cockpit
The combination of KVM and Cockpit offers several benefits, including improved manageability, scalability, and security. With Cockpit, you can easily manage your KVM virtual machines, including creating, starting, stopping, and deleting VMs. Additionally, Cockpit provides a dashboard view of your KVM infrastructure, allowing you to monitor performance, utilization, and other key metrics.
