What is KVM + Cockpit?
KVM (Kernel-based Virtual Machine) is an open-source virtualization solution for Linux, while Cockpit is a web-based management interface for Linux servers. Together, KVM + Cockpit provide a powerful and user-friendly platform for managing virtual machines (VMs) and containers. This combination allows administrators to easily deploy, manage, and monitor their virtual infrastructure.
Main Benefits
The integration of KVM and Cockpit offers several benefits, including simplified management, improved scalability, and enhanced security. With KVM + Cockpit, administrators can create and manage VMs and containers, allocate resources, and monitor performance, all from a single, intuitive interface.
