Proxmox VE is a free, open-source, Debian-based virtualization platform that combines KVM virtual machines and LXC containers in a single web-based management panel. This guide explains the core concepts and walks through installing Proxmox VE on a bare-metal server and creating your first virtual machine.
Understanding Proxmox VE starts with distinguishing four fundamental building blocks.
KVM-based full virtualization; runs its own kernel, supports different operating systems including Windows, and is fully isolated from the hardware.
A lightweight Linux container that shares the host's OS kernel; consumes far fewer resources than a VM and starts much faster.
A single physical server running Proxmox VE; multiple nodes can be joined together to form a cluster.
The layer where virtual disks are stored; ZFS provides snapshots and data integrity, while LVM-thin is a simple, fast option.
VMware's post-2024 licensing changes pushed many administrators to look for alternatives, and Proxmox VE has emerged as one of the leading options.
All of Proxmox VE's features are usable without paying a license fee; the optional support subscription only adds enterprise support and access to a curated repository, it doesn't restrict core functionality.
Workloads that need full isolation run as KVM virtual machines, and lightweight, fast workloads run as LXC containers — both managed from the same web interface.
Proxmox Backup Server integration and the built-in vzdump tool provide scheduled, incremental backups without buying a separate product.
Cluster management, storage, networking and user authorization are all handled from a single web interface; no separate management server (like vCenter) is required.
Proxmox VE installs directly onto hardware from the official ISO image and becomes usable through its web-based management interface right after installation.
Download the current Proxmox VE ISO from the official proxmox.com download page and write it to a USB drive.
Boot the server from the USB drive and choose the target disk, time zone and administrator password in the installation wizard.
During installation, set the server's static IP address, gateway, and choose ZFS or ext4 for the root file system.
Once installation completes, open https://server-ip:8006 and log in as root to access the management panel.
Check in the web interface that the vmbr0 network bridge and the selected storage pool (local-lvm or ZFS) are configured correctly.
Use the 'Create VM' wizard in the web interface to create and start a new virtual machine from an ISO image.

Yes, all features of Proxmox VE are available for free through the No-Subscription (community) repository. The paid subscription provides tested, stable package updates through the Enterprise repository, official technical support and priority bug fixes; it doesn't restrict core virtualization functionality.
ESXi only supports full virtual machines (VMs) and requires a separate management product like vCenter; Proxmox VE manages both KVM virtual machines and lightweight LXC containers from a single free web interface, and cluster management doesn't require any extra component.
For testing and learning, a CPU with virtualization support (Intel VT-x/AMD-V), 2 GB RAM and 32 GB of disk are enough; for running several VMs in production, at least 8 GB RAM and a server motherboard with ECC support is recommended.
Yes, but the VPS provider must support nested virtualization (VT-x/AMD-V passthrough); without it, only LXC containers can run — KVM virtual machines won't start.
Yes, since KVM provides full virtualization, Windows Server and desktop Windows versions run without issues; installing the VirtIO drivers inside the VM is recommended for the best disk and network performance.
The built-in vzdump tool can create scheduled full or incremental backups; a separately installed Proxmox Backup Server adds deduplicated, efficient incremental backups and one-click restore.
