Proxmox VE Introduction

1. Introduction

Proxmox Virtual Environment (VE) is an open-source server virtualization management solution based on KVM (Kernel-based Virtual Machine) and LXC (Linux Containers). It allows you to manage virtual machines, containers, storage, and networking in a single platform.

2. Key Concepts

Virtual Machines (VMs): Fully isolated environments that run an operating system.
Containers: Lightweight, resource-efficient environments that share the host OS kernel.
Storage: Management of different storage types such as local, NFS, and Ceph.
Networking: Configuration of virtual networks for VMs and containers.
High Availability: Features to ensure uptime and reliability of critical services.
