1. Proxmox VE, so what is it? 🤔
Proxmox VE is an open source based server virtualization management platform. In simple terms, it’s an operating system that allows you to create and manage multiple independent virtual machines (virtual machines, VMs) or containers inside one physical computer (server).
- Hypervisor type: Proxmox VE is a Type-1 (bare-metal) hypervisor, which means that it is not installed on top of a separate operating system (Windows, Linux), but is installed directly on the physical server hardware and acts like an OS. This allows for the most efficient use of hardware resources.
- Core technologies:
- KVM (Kernel-based Virtual Machine): A powerful virtual machine technology that allows you to fully virtualize a variety of operating systems, including Windows, Linux, and more.
- LXC (Linux Containers): A lightweight container technology that delivers extreme efficiency and fast startup speeds with operating system-level virtualization.
- Unified management: All of these virtualized environments can be easily managed through a powerful and intuitive Web-based user interface (Web UI). 🌐.

2. Why choose Proxmox VE? ✨
With so many virtualization solutions out there, why Proxmox VE? The answer lies in the compelling advantages of Proxmox VE.
- **💰 Cost-effective: completely free and open source!
- One of the biggest advantages of Proxmox VE is that it’s free. Commercial virtualization solutions (e.g. VMware vSphere, Microsoft Hyper-V), while powerful, come with significant licensing costs. Proxmox VE is open source, meaning anyone is free to download, use, and modify it. Of course, there are paid subscriptions for enterprise users, but the basic features are all free.
- **🤩 Overwhelming ease of use: intuitive web UI!
- The “virtualization is hard?” stereotype doesn’t apply to Proxmox VE. Thanks to the intuitive web UI, where all setup and management is done through a web browser, even first-time users can easily create virtual machines, set up storage, and configure networks. No need to memorize complex commands.
- **💪 Highly flexible: The synergy of VMs and LXC!!!
- Proxmox VE simultaneously supports full-fledged virtual machines (VMs) based on KVM and lightweight containers (LXCs) based on LXC. You can use VMs for applications with heavy operating systems or special hardware requirements, and LXC containers for running multiple services quickly and lightly, maximizing the efficiency of resource utilization.
- **🛡️ Strong reliability and scalability: Clustering and HA!
- Multiple Proxmox VE servers can be grouped together to form a cluster. This enables High Availability (HA), so that if one node (server) within the cluster fails, the virtual machines are automatically migrated to another node to minimize service interruption. 🤯 This is a key feature for uninterrupted service.
- 🤝 Active community support:.
- As an open source project, Proxmox VE boasts a very active user community. You can find tons of information on the official forums, wiki, and various blogs and YouTube channels, and when you run into problems, you can get help quickly.

3. What can Proxmox VE be used for 🏠🏢?
Proxmox VE can be utilized in a variety of environments, from home users to small and medium-sized businesses.
- Personal home labs and personal server deployments:* Building your own server.
- **You can create your own server by installing Proxmox VE on an old PC or mini PC lying around at home.
- Example: On one Proxmox VE server, you can run a 📺 Plex media server VM, ☁️ Nextcloud file sharing VM, 🤖 Home Assistant smart home control LXC container, and a VM for hosting your personal website.
- Consolidate and streamline your small business servers:.
- *Consolidate multiple physical servers (file servers, web servers, DB servers, etc.) onto just one powerful physical server by installing Proxmox VE and consolidating all services into virtual machines within it, increasing operational efficiency and reducing power consumption.
- Build development and test environments:.
- Before developing new software or applying updates to existing systems, you can easily clone and destroy test environments by utilizing the snapshot feature. No worries if you make a mistake!
- Delivering web hosting and application services:.
- With the power and reliability of Proxmox VE, you can efficiently host multiple websites or applications.

4. Getting Started with Proxmox VE (Simple Guide) 🧑💻
Getting started with Proxmox VE is not as difficult as you might think, here are some very simple steps.
- Prepare your hardware: Prepare the server or PC where you will install Proxmox VE. At a minimum, you’ll need a CPU (with VT-x/AMD-V virtualization support), plenty of RAM, and an SSD/HDD for the OS installation.
- Download ISO:** Download the latest version of the ISO file from the Proxmox VE official website.
- Create installation media:** Place the downloaded ISO file on a USB drive and make it bootable using a tool like Rufus.
- Install:** Insert the USB into the prepared server and boot it to proceed with the Proxmox VE installation process. Most of the process is done through a graphical interface, requiring only a few network settings and password settings.
- Connect:** Once the installation is complete, connect via a web browser to the IP address of the server where Proxmox VE is installed and the port you specified (8006 by default). (Example:
https://192.168.1.100:8006)

5. Learn more about Proxmox VE’s core features 🛠️
To better understand the appeal of Proxmox VE, let’s take a closer look at its key features.
- Virtual machine (VMs) management:
- KVM-based: Fully supports hardware virtualization by utilizing CPUs with Intel VT-x or AMD-V support. Thanks to this, you can expect almost the same performance as running on a physical machine.
- Multiple OS support: You can install many x86/x64-based operating systems as guest OS, including Windows Server 2022, Windows 10, Ubuntu Server, CentOS, Debian, and many more.
- Snapshots: Save the state of your VM at a specific point in time to quickly restore it when needed. This is useful when you make a fatal mistake in your dev/test environment.
- Container (LXC) management:
- Lightweight: Unlike VMs, they share the kernel of the host OS rather than booting a separate kernel, making them much lighter, faster to start up, and more resource efficient.
- High performance: With less virtualization overhead, you can expect fast performance like Docker containers.
- Examples: Separate services such as web servers (Nginx, Apache), databases (MySQL, PostgreSQL), and messaging queues (RabbitMQ) can be run in LXC containers to maximize resource efficiency.
- Integrated storage management:.
- Proxmox VE supports integrated management of various storage technologies.
- Logical Volume Manager (LVM): Flexible partition management.
- ZFS: A next-generation file system that provides powerful data integrity checks, snapshots, and replication. 💾
- Ceph: A distributed storage system that provides high availability and scalability by distributing storage across multiple Proxmox VE nodes.
- NFS, iSCSI: Allows you to connect and use external network storage.
- Networking:
- Linux Bridge: Uses a physical network interface as a virtual switch to allow multiple VMs/LXCs to connect to a physical network.
- VLAN: Supports virtual local area networks (VLANs) to logically separate networks and increase security. Even complex network configurations are OK!
- Clustering and High Availability (HA):
- Multiple Proxmox VE nodes can be clustered and managed together.
- Live Migration: * You can move a running VM/LXC to another node without service interruption. This is very useful during system maintenance.
- High Availability (HA): If a particular node fails, the VM/LXC running on that node will automatically restart on another healthy node in the cluster to minimize service disruption. Shared storage is essential for this.
- Backup and Restore:.
- Built-in backup capabilities make it easy to backup and restore all VMs and LXCs. Scheduling capabilities also allow for regular backups, giving you peace of mind. 💾
- Firewall:
- Proxmox VE provides host-level firewall capabilities, giving you fine-grained control over traffic entering and leaving your virtual environment. 🔒
