Virtualization - credativ®

What is PegaProx?

PegaProx is becoming a central platform for modern Proxmox VE-based virtualization, offering a free and open source approach to managing virtualization at scale. It is increasingly seen as a powerful multi cluster solution designed for more demanding enterprise setups. Where traditional tools start to fall short and even the native Proxmox Datacenter Manager does not yet cover many key requirements, PegaProx fills that gap by providing a consistent and clearly structured way to manage complex infrastructures.

As a central control unit, PegaProx unifies all aspects of cluster management (including multi-cluster management and Proxmox Backup Server) in a single interface, creating a consistent view of all resources, workloads, and systems. Administrators no longer need to switch between individual clusters, nodes, or isolated monitoring solutions; instead, they gain a fully integrated environment that significantly increases transparency, control, and efficiency. Especially in growing infrastructures with multiple clusters, this approach becomes a decisive advantage. In daily operations, virtualization managers repeatedly face the same challenges. Resources must be monitored across clusters, bottlenecks identified early, and maintenance work coordinated without jeopardizing availability. At the same time, increasing complexity raises the risk of misconfigurations, inconsistent states, and unplanned outages. Other features familiar from other well-known enterprise virtualization solutions also play a central role in PegaProx. PegaProx addresses these problems with a consistently centralized architecture, real-time metrics, and intelligent automation that simplifies operational processes and implements previously missing functionalities.

PegaProx for Proxmox: Cluster Overview

Developed by a small, focused team with strong practical relevance, which includes our colleague Florian Paul Azim Hoberg (also known as gyptazy) as a core contributor, PegaProx places particular emphasis on real requirements from the enterprise environment. Functions such as managing multiple clusters as a logical unit, a global overview of snapshots including a clean-up function, or the dynamic distribution of workloads based on current resource data (ProxLB) are not theoretical concepts, but specifically developed solutions for productive use. The result is a platform that elevates Proxmox VE to a new level and offers companies a powerful, scalable, and understandable solution for their virtualization strategy.

What does PegaProx offer?

PegaProx combines a variety of functions specifically developed for the professional operation of Proxmox VE-based infrastructures. The focus is clearly on central control, automation, and transparency across multiple clusters. Instead of fragmented tools, an integrated platform emerges that simplifies daily operations and reliably maps complex enterprise requirements.

PegaProx with central, aggregated logging overview

To align this with the ProxTools Collection, created by @gyptazy, such as ProxLB, ProxCLMC, ProxPatch, ProxSnap, and ProxLog, have also been integrated and now offer a way to administer them via PegaProx’s graphical interface for easy usability. Key functions include:

• Multi-Cluster Management
• Unified Dashboard
• Multi-Tenancy & End-User Self-Service Portal
• Live Metrics
• Cross-Cluster Load Balancing
• Live Migration
• Cross-Cluster Live Migration
• High Availability and Automatic Failover
• Snapshots and Snapshot Replication
• Centralized Snapshot Overview
• Backup Management including Verification
• Role-Based Access Control and Multi-Tenancy
• Integration of External Authentication Systems
• Automation and Scheduled Tasks
• Rolling Updates / Patch Management for Cluster Nodes
• Integrated Syslog Server
• Ceph Management
• Audit Logging and Monitoring Alerts
• and much more

This represents only some of the capabilities PegaProx already offers today. Many other functions and continuous developments constantly expand the platform, closely aligning with the real requirements of modern virtualization environments. A complete overview of all features, technical details, and current developments can be found on the official PegaProx GitHub page, where all functions are transparently documented and continuously updated.

Installation & Configuration of PegaProx

The installation of PegaProx is deliberately designed to be flexible, covering a wide range of environments and requirements. Whether for quick evaluation, integration into existing infrastructures, or productive enterprise use, PegaProx can be deployed in several ways and seamlessly integrated into existing Proxmox VE landscapes. All installation methods pursue the same goal: the simplest, most reproducible, and transparent deployment possible without unnecessary complexity.

The following options are available for installation:

• Bash Script
  A quick and easy way to get started using an automated installation script (however, we strongly advise against this method, even though it is becoming increasingly popular again):
  curl -sSL https://raw.githubusercontent.com/PegaProx/project-pegaprox/refs/heads/main/deploy.sh | sudo bash
• Docker Container Image
  Deployment as a container for maximum portability and easy integration into existing container environments
• LXC Appliance
  Prebuilt LXC template for direct use in Proxmox VE with minimal setup effort
• VM Appliance
  Fully preconfigured virtual machine for fast and isolated commissioning
• Debian Package
  Native installation via a Debian package for systems that are intentionally to be operated without containers
• Debian Repository
  Central package source for easy updates, versioning, and integration into existing package management processes

Regardless of the chosen method, the basic configuration is quickly completed, so PegaProx is available as a central management platform for multiple Proxmox VE clusters within a very short time.

Conclusion

PegaProx is rapidly developing into one of the most exciting solutions in the field of Proxmox VE-based virtualization and is already generating great enthusiasm in the community. Many companies already see PegaProx as the central platform they have been missing in the Proxmox ecosystem, especially when it comes to multi-cluster management, automation, and a consistent overall overview.

The clear structure, practical range of functions, and consistent focus on real requirements in the enterprise environment clearly demonstrate the platform’s potential. PegaProx not only closes existing gaps but also defines a new standard in many areas for managing complex virtualization landscapes.

Despite this positive development, it should be noted that PegaProx is currently still in its beta phase. Even though much already functions stably and thoughtfully, problems or unexpected behavior can occur at any time. For productive environments, its use should therefore be carefully considered and, if necessary, first implemented in test or staging scenarios.

Errors, wishes, or suggestions for improvement can be reported at any time via the project on GitHub. Additionally, the developers are available directly via the gyptazy projects Discord server for exchange and support.

Proxmox VE® has established itself as an open-source virtualization platform, but even experienced IT administrators encounter treacherous pitfalls during cluster configuration. A single Proxmox® cluster error can cripple your entire enterprise infrastructure and lead to costly downtime. The good news: most of these problems are predictable and avoidable.

From split-brain scenarios to flawed backup strategies – these ten most common virtualization errors have caused countless IT projects to fail. Learn how to avoid these critical stumbling blocks and elevate your Proxmox® cluster management to a professional level. (more…)

Proxmox® VE is fundamentally free – the Community Edition is released under AGPL and can be used completely free of charge. For companies that require professional support and extended features, there are paid Enterprise Subscriptions. Additionally, there are alternative service offerings that replace vendor support. The actual costs depend on your specific requirements, the desired support level, and additional factors such as hardware and administration.

What is Proxmox and why is it interesting for companies?

Proxmox VE is an open-source virtualization platform that combines KVM virtualization and LXC containers on a unified web interface. The software enables companies to efficiently utilize physical servers by running multiple virtual machines on a single host system.

For businesses, Proxmox offers several decisive advantages: The platform reduces hardware costs through optimized server utilization, simplifies IT management through central administration, and provides high availability through cluster functions. As an open-source solution, there are no license costs for the basic functions.

The platform is characterized by a flexible cost model. While commercial hypervisor solutions often demand significant license fees, you can use Proxmox without restrictions on virtualization functions. Small and medium-sized enterprises, in particular, benefit from this cost-efficient approach.

Which Proxmox versions are available and what do they cost?

Proxmox offers two main versions: the free Community Edition and the paid Enterprise Subscription. The Community Edition – not to be confused with the Community Subscription – includes all virtualization functions without functional limitations but uses free update repositories.

The Enterprise Subscription offers various support levels with different response times and ticket quotas. Current prices and service scopes can be found at https://www.proxmox.com/de/produkte/proxmox-virtual-environment/preise.

The main difference lies not in the features, but in the support level and update repositories. Enterprise customers gain access to stable, tested updates and professional support directly from the Proxmox team. The Community Edition offers the same technical capabilities, but without guaranteed support services. In between, there is also the so-called Community Subscription, where the customer gets access to the Enterprise repositories for a small annual fee. Proxmox Server Solutions points out that they do not consider the Community Subscription to be Enterprise-ready, as there is no claim to support from the manufacturer. However, it must be noted here that there are alternative support offerings for this version, such as credativ’s Virtualization Services for Proxmox.

When is a Proxmox Enterprise Subscription really worthwhile?

An Enterprise Subscription is worthwhile if your company relies on stable, productive virtualization environments and requires professional support. Critical business applications that demand high availability justify the investment in Enterprise support.

Decision criteria for switching include:

• Productive environments with critical applications
• More than 10–15 virtual machines in operation
• Lack of internal Linux® and virtualization expertise
• Compliance requirements that necessitate professional support
• 24/7 operation without internal night shifts

The Return on Investment is demonstrated through reduced downtime, faster problem resolution, and predictable update cycles. If the cost of a one-hour system outage exceeds the annual subscription costs, the Enterprise version clearly pays off.

credativ® as an open-source company recommends that customers acquire at least the Community Subscription to gain access to stable repositories and simultaneously support the project.

What are the hidden costs of Proxmox implementations?

In addition to licensing costs, other expenses often underestimated arise. Hardware requirements, training, ongoing administration, and backup solutions can significantly influence the total costs. Realistic budget planning should consider these factors.

Additional cost factors include:

• Hardware: Servers, storage, network equipment (often 70–80% of total costs)
• Training: 2–5 days of training per administrator
• Administration: 10–20% of a full-time position for smaller environments
• Backup software: Various solutions available
• Monitoring tools: Diverse options depending on requirements
• Disaster Recovery: Hardware and location costs

A realistic total cost estimate for a small business environment over three years is €15,000–€50,000, with hardware accounting for the largest share. Plan for approximately 20–30% buffer for unforeseen requirements.

How does Proxmox differ from other virtualization solutions in terms of cost?

Proxmox offers a flexible cost model compared to commercial solutions. While VMware vSphere® or Microsoft® Hyper-V® incur licensing costs, Proxmox® only has optional support costs. This can significantly reduce the Total Cost of Ownership.

Further differences emerge when considering TCO: Proxmox requires more Linux® expertise but offers complete control over the system. Commercial solutions often provide more extensive management tools but incur ongoing licensing costs. Some integrate seamlessly into Windows® environments but require corresponding server licenses.

The main advantage of Proxmox lies in its scalability without license tier jumps. While commercial solutions can become exponentially more expensive with growing infrastructure, Proxmox costs remain linearly predictable.

Proxmox® installation is a crucial step for companies looking to implement a professional virtualization solution. This comprehensive guide will walk you through the entire Proxmox VE installation process and help you set up a stable hypervisor environment. You will need basic Linux® knowledge and approximately 2–3 hours for the complete installation and basic configuration. For this Proxmox guide, you will need a dedicated server with at least 4 GB RAM, an 8 GB USB stick, and access to the target computer’s BIOS. After completing these steps, you will have a fully functional Proxmox VE system for your server virtualization. Please note, however, that this hardware configuration is far too limited for a production system. For initial steps, however, it is suitable. (more…)

Proxmox® offers four storage options: ZFS for local high-performance storage with integrated snapshots and compression, Ceph for distributed high-availability systems, NFS for file-based network storage, and iSCSI for block-based enterprise solutions. The choice depends on your performance requirements, budget, and infrastructure size. Each option is suitable for specific virtualization scenarios.

The decision for credativ Proxmox Enterprise Support depends on your business requirements, the criticality of your virtualization environment, and your available internal IT resources. Enterprise Support offers professional assistance, stable updates, and advanced features, while the Community Edition remains free but without guaranteed support. This analysis will help you make the right decision for your company.

What is Proxmox Enterprise Support and how does it differ from the Community Edition?

Proxmox Enterprise Support is the paid version of the virtualization platform, offering professional support, stable updates, and access to enterprise repositories. The community repositories provide the same basic functionality for free, but without a support guarantee and with less thoroughly tested updates. Both versions are provided by Proxmox Server Solutions GmbH under the AGPL license. However, there is an important additional distinction: those who wish to save costs can gain access to the enterprise repositories by purchasing a so-called Community Subscription. This, however, only includes access and no further support.

The most significant difference lies in the support level. Enterprise customers receive direct access to the Proxmox team for technical issues, while community users rely on forums and community assistance. Enterprise Support includes various service levels, from Standard to Premium, with different response times.

The update cycles differ significantly. Enterprise repositories contain thoroughly tested, stable updates optimized for production environments. Community updates appear more frequently but are less intensively tested and can be more unstable.

Additional enterprise features include advanced backup options, cluster management tools, and specialized monitoring options. These features are not available in the Community Edition and are specifically tailored to enterprise requirements.

When is Proxmox Enterprise Support worthwhile for businesses?

Enterprise Support is particularly worthwhile for companies with critical production environments, limited internal IT resources, or strict compliance requirements. Companies with approximately 50 employees or more, or those with high availability demands, generally benefit from professional support.

A critical factor is the availability requirements of your systems. If outages cause high costs or significantly disrupt business processes, investing in Enterprise Support is justified. This applies particularly to e-commerce, financial service providers, or manufacturing operations.

Internal IT expertise plays a crucial role. If specialized virtualization experts are lacking in the team, Enterprise Support provides valuable assistance with complex problems. Smaller IT teams particularly benefit from the available expertise.

Compliance requirements may necessitate Enterprise Support. Many industries require documented support for audit purposes. Enterprise Support provides the necessary documentation and traceability for regulated environments.

What does Proxmox Enterprise Support cost and what licensing models are available?

Proxmox Enterprise Support is licensed per CPU socket with various support levels. Prices start at 120 Euros per socket per year for access to the enterprise repositories without support, while Premium Support incurs significantly higher costs but offers faster response times. (As of January 1, 2026)

The Basic or Standard package includes access to enterprise repositories, updates, and email support during business hours. This level is suitable for smaller environments without particularly high availability requirements.

Premium Support offers shorter response times and extended services. The costs are significantly higher, but for critical systems, they are well justified by minimized downtime.

Additional cost factors include the number of CPU sockets, desired response times, and special services such as on-site support or individual training. Larger deployments often receive volume discounts.

What alternatives are there to Proxmox Enterprise Support?

Alternatives to official Enterprise Support include Community Support, third-party service providers, in-house expertise development, or hybrid approaches. Each option offers different advantages and disadvantages depending on the company’s situation.

Community support via forums and documentation remains free but offers no guarantees for response times or problem resolution. Experienced IT teams can often find solutions independently, while less experienced teams may struggle.

Support from specialized third-party providers like credativ GmbH can be more cost-effective than official Enterprise Support. These providers often understand local requirements better and offer more flexible service packages. However, quality varies among providers.

Developing in-house expertise through training and certifications offers long-term independence but requires investment in personnel and time. Hybrid approaches combine internal expertise with external open-source support for particularly complex problems.

The correct setup of a Proxmox® Backup Server is crucial for data security in businesses. This guide shows you how to fully configure Proxmox PBS from installation to automation.

Why Proxmox Backup Server is a professional solution

Proxmox Backup Server offers businesses a cost-efficient backup solution with a flexible licensing model. The open-source solution integrates seamlessly into existing Proxmox VE environments and provides professional features without the overhead of proprietary alternatives.

Key advantages of Proxmox PBS:

• Automatic deduplication significantly reduces storage requirements
• End-to-end encryption protects sensitive data
• Incremental backups minimize network load
• Web interface simplifies management
• Scalability from small to large environments

Direct integration with Proxmox VE enables VM backups without additional agents. Furthermore, other data sources can be integrated via standard protocols.

System Requirements and Preparation

Before installation, check all hardware and software requirements to ensure stable operation.

Minimum hardware requirements:

• CPU: 64-bit processor with at least 2 cores
• RAM: 4 GB (8 GB recommended for larger environments)
• Storage: 32 GB for the system plus separate backup storage
• Network: Gigabit Ethernet recommended

The backup server requires a fixed IP address and access to all systems to be backed up. Ensure that your firewall rules allow traffic on Port 8007 (web interface) and Port 8009 (backup protocol).

Plan storage requirements realistically: Calculate the space needed for your full backups plus 20–30% for metadata and deduplication overhead.

Install and Configure Proxmox Backup Server

Download the latest Proxmox Backup Server ISO image from the official website. Then, create a bootable USB stick or mount the ISO directly in your virtualization environment.

Start the system from the installation medium. The installer will guide you step-by-step through the basic configuration:

1. Select target disk for installation
2. Configure time zone and keyboard layout
3. Set a secure root password
4. Configure network settings with a fixed IP
5. Confirm installation parameters and start installation

After restarting, you can access the web interface at https://your-ip:8007. Log in with the root account and check the network and DNS configuration under “Administration”.

Create additional user accounts for daily operation. The root account should only be used for administrative tasks, not for regular backup jobs. A detailed step-by-step guide can be found in our older article.

Set up Backup Repositories and Storage

Navigate to “Datastore” and click “Add Datastore” to set up the first data store for your backups. Assign a meaningful name and select the target path. For optimal performance, separate hard drives or RAID arrays are recommended.

Important configuration options in the Datastore:

• GC Schedule: Automatic garbage collection for deleted backups
• Prune Schedule: Automatic deletion of old backups according to defined retention rules
• Verify Schedule: Regular integrity check of backup data

PBS automatically activates deduplication. It detects identical data blocks and stores them only once – for VMs with similar operating systems, savings of 50–80% are realistic.

Test the datastore with a small test backup before setting up production jobs. Check write speed and available storage space.

Create and Automate Backup Jobs

For Proxmox® VE VMs, configure backup jobs directly in the VE interface under “Datacenter” > “Backup”. Create a new job there with the following parameters:

1. Select PBS as storage target
2. Define VMs or containers for backup
3. Set schedule (daily, weekly)
4. Configure retention rules (keep-daily, keep-weekly, keep-monthly)
5. Enable email notifications

For other data sources, use the Proxmox® Backup Client. Install it on the source systems and control backup execution via cron jobs and backup scripts.

Run each backup job manually once before automation. Check the log files for errors and ensure that all desired data is fully captured.

Monitoring: Configure email notifications for successful and failed backups. Regularly monitor backup sizes and runtimes to detect deviations early.
