Proxmox VE stands as a formidable open-source virtualization platform, empowering users to manage and deploy virtual machines (VMs) and containers on a singular hardware node.
Rooted in the Debian distribution, Proxmox VE provides an intuitive web interface, accompanied by support for Kernel-based Virtual Machines (KVM) and Linux Containers (LXC).
It also boasts a myriad of supplementary features, positioning it as an exemplary solution for businesses and individuals seeking to leverage the benefits of virtualization and containerization.
In this blog post, we will delve into Proxmox VE and illustrate how it can aid you in swiftly establishing an environment for virtual machines and containers.

Section 1: An In-Depth Look at Proxmox VE
Proxmox VE is an all-encompassing virtualization solution that merges the capabilities of KVM for comprehensive virtualization and LXC for lightweight, OS-level virtualization.
Its adaptability and user-friendliness have garnered popularity among IT professionals and hobbyists alike. Notable features of Proxmox VE encompass:
- User-friendly web interface: Proxmox VE’s web interface simplifies the process of creating and managing VMs and containers. The web interface allows users to monitor resource usage, configure storage, and manage network settings without the need for command-line expertise.
- Support for multiple storage backends: Proxmox VE is compatible with various storage backends, including local storage, network-attached storage (NFS, CIFS), and distributed storage (Ceph, GlusterFS). This flexibility enables users to choose the most suitable storage solution for their specific needs.
- Live migration: Proxmox VE supports live migration of VMs and containers between nodes without service interruption. This feature is invaluable for maintaining high availability and load balancing in clustered environments.
- High availability: Proxmox VE offers built-in high availability (HA) features, allowing VMs and containers to be automatically restarted on another node in case of hardware failure. This ensures continuous service and minimizes downtime.
- Backup and restore: Proxmox VE includes robust backup and restore capabilities, enabling users to create full or incremental backups of VMs and containers. Backups can be stored locally or on remote storage servers for added redundancy.
- Open-source and cost-effective: Proxmox VE is an open-source solution, which means it is free to use and modify. This makes it a budget-friendly alternative to proprietary virtualization platforms.
Section 2: Installing Proxmox VE
To harness the power of Proxmox VE and quickly create an environment for virtual machines and containers, you first need to install the platform on a compatible system.
We recommend using a Debian-based system with a 64-bit processor, at least 4 GB of RAM, and 20 GB of free disk space for Proxmox VE installation.
Installation steps include:
- Preparing the Debian system: Update the package index and upgrade existing packages. Install required packages such as curl, wget, apt-transport-https, gnupg2, and ca-certificates.
- Adding the Proxmox VE repository: Import the Proxmox VE repository key and add the repository to your Debian system.
- Installing the Proxmox VE packages: Install the Proxmox VE packages, including proxmox-ve, postfix, and open-iscsi. Configure the Postfix mail server as needed.
- Configuring the network: Set up a network bridge for VM and container communication. Modify the /etc/network/interfaces file to create a network bridge with the desired IP address and gateway.
- Configuring the firewall (optional): If you have a firewall enabled on your Debian system, allow the necessary ports for Proxmox VE to function correctly.
- Rebooting the system: After installing and configuring Proxmox VE, reboot the system to complete the installation process.
Section 3: Creating Virtual Machines and Containers in Proxmox VE
Once Proxmox VE is installed on your Debian system, you can start creating VMs and containers using the web interface or command-line tools. Here’s how to get started with both methods:
- Using the web interface:
a. Access the Proxmox VE web interface by navigating to
https://<your-server-ip-address>:8006
in your web browser. Log in using your Debian system’s “root” username and password.
b. To create a VM, click on “Create VM” in the upper right corner of the web interface. Follow the wizard to configure the VM’s settings, such as the operating system, storage, and network.
c. To create a container, click on “Create CT” in the upper right corner of the web interface.
Follow the wizard to configure the container’s settings, such as the template, storage, and network. - Using command-line tools:
a) To create a VM, use theqmcommand along with the appropriate options to configure the VM’s settings. For example, to create a VM with an Ubuntu ISO image, you can use the following command:
qm create 100 --name ubuntu-vm --memory 2048 --net0 virtio,bridge=vmbr0 --cdrom /var/lib/vz/template/iso/ubuntu-20.04.2-live-server-amd64.iso
b) To create a container, use the pct command along with the appropriate options to configure the container’s settings. For example, to create a container with an Ubuntu template, you can use the following command:
pct create 101 local:vztmpl/ubuntu-20.04-standard_20.04-1_amd64.tar.gz --hostname ubuntu-ct --memory 1024 --net0 name=eth0,bridge=vmbr0,ip=dhcp
Section 4: Managing Virtual Machines and Containers
Proxmox VE provides various tools and features to manage VMs and containers effectively:
- Resource monitoring: The web interface displays real-time resource usage statistics, including CPU, memory, and disk usage for each VM and container. This allows you to monitor the performance of your virtual environments and make adjustments as necessary.
- Snapshots: Proxmox VE supports creating snapshots of VMs and containers, allowing you to save the current state of a VM or container and revert to that state later if needed. This is particularly useful for testing software updates or configuration changes.
- Clustering: Proxmox VE allows you to create clusters of multiple Proxmox nodes, providing a centralized management interface for all nodes in the cluster. This simplifies administration and enables advanced features such as live migration and high availability.
- Backup and restore: Use Proxmox VE’s built-in backup and restore capabilities to create full or incremental backups of your VMs and containers, ensuring data protection and allowing you to recover from unexpected failures.
Conclusion
Proxmox VE is an incredibly powerful and versatile virtualization platform that streamlines the creation and management of virtual machines and containers.
By following this guide, you have equipped yourself with the knowledge to harness the power of Proxmox VE, enabling you to optimize your workflows and maximize efficiency.
Whether you’re a business owner looking to deploy a virtualized infrastructure or an individual exploring virtualization, Proxmox VE offers an ideal solution to meet your needs.
