What is KVM + Cockpit?

KVM (Kernel-based Virtual Machine) and Cockpit are two powerful tools that work together to provide a robust virtualization and containerization solution. KVM is a hypervisor that allows users to run multiple virtual machines on a single physical host, while Cockpit is a web-based interface that simplifies the management of these virtual machines and containers.

Main Features of KVM + Cockpit

KVM + Cockpit offers a range of features that make it an attractive solution for virtualization and containerization. Some of the key features include:

• Virtual machine management: KVM + Cockpit allows users to create, manage, and delete virtual machines with ease.
• Container management: Cockpit provides a simple and intuitive interface for managing containers, including the ability to create, start, stop, and delete containers.
• Networking: KVM + Cockpit provides advanced networking features, including support for VLANs, bonding, and bridging.
• Storage: KVM + Cockpit supports a range of storage options, including local storage, NFS, and iSCSI.
