Proxmox VE Reviews

Proxmox VE is 100% free to use, you only pay for support directly from Proxmox Server Solutions GmbH. It is incredibly easy to deploy, it can be installed from an ISO or on top of an existing Debian system. Proxmox VE is very versatile - it supports LXC containers as well as QEMU/KVM virtual machines. Documentation for Proxmox VE is very well-made and complete and community support is available on the forums for free. Proxmox natively supports HA clusters. Proxmox uses open-source hypervisors instead of closed source hypervisors like Citrix XenServer.

Proxmox is still missing some functions like web-based user management and automatic IP allocation from a pool. Some functions are not available in the web UI and must be done via the CLI. Proxmox is not suitable for selling VMs to customers, as it does not have a customer-facing panel. It is designed for administrators only, not necessarily endusers. Initial setup (especially network) can be a bit of a pain, especially if using a provider that requires custom network configuration like Hetzner or OVH.

Make sure you work out your architecture before putting PVE into production.

We manage several dedicated servers with various providers around the world. We used to use Docker containers to run our applications but Docker proved to be very cumbersome, as not every application supports Docker out of the box. With Proxmox, we can simply create a virtual machine and install the application like you would on a bare-metal machine, saving us time.

I love this admin panel for virtualization of servers, what makes it special is that open source, is super easy to use to achieve create VPS, cloud. You can have many operating systems available for installation including CentOS, Debian, Ubuntu and Windows if you want to create a Windows machine.

Proxmox not dislike at all, I always found it super great to work with this virtualization panel of servers, has a special tool is that you have to connect via SSH to the servers with root access from the same panel. This proxmox panel is very easy to install on any Linux operating system.

I recommend Proxmox for all those people and companies that require a virtualization administration of servers in a complete, simple, friendly and without much hassle for use as an administrator. If your goal is to sell dedicated servers, VPS and Windows virtual machines, this is a super tool for that, remember that you must have a server to install this program with a lot of hard disk resource, RAM and CPU.

With this panel proxmox I have solved many business issues because my company sells dedicated servers, VPS and virtual machines windows, this panel has been wonderful for me to create all these machines and offer them to my clients

Proxmox is a solution that every IT administrator should be familiar with. The main advantage of Proxmox is the fact that this open-source system enables us to create and manage virtual machines with a clear interface. One of the advantages of Proxmox is the ability to adapt machines to our preferences and to support UEFI and BIOS. Proxmox is a very stable solution to use standard tools, including Red Hat Cluster Suite, as well as sharing command line tools, making the maintenance and use of Proxmox VE reliable and easier to manage to quickly restore order when something stops.

People starting their adventure with the management server may have minor problems with setting up the first server.

If you are looking for a solution that will allow you to create virtual systems on your dedicated server/workstation, you should consider trying Proxmox, especially since it is available for free.

Thanks to the use of Promox I was able to divide the dedicated server into KVM, thanks to which I saved a lot of money by buying servers from a reseller.

Simplicity of use and moderate learning curve.

It is a very mature product (more than 10 years)

Easily create and manage VM (KVM) and containers (LXC) through a comprehensive and intuitive web interface that is constantly evolving.

Support for multiple storage types: ZFS, NFS, CIFS, LVM, iCSI, Cepth, GlusterFS... and more

Comprehensive virtualization solution: Role-based management, backups, storage virtualization, firewall, high availability (Cluster), REST AP,I templates, live migration...

Free support via the official forum is very effective.

Very well documented through a very complete wiki, the latest versions have documentation integrated in the web interface.

The web interface is the best thing about this product, it is designed to be easy to use, without hidden menus or excessive clicks. VNC management of virtual machines is also done via the web, using the non-VNC client. If you want to enjoy a desktop experience on the VMs you can easily use SPICE.

A visual network manager is missing as in other similar products. Via web interface there are options to enable/disable NICs or the bond configuration. But if we want to manage virtual networks in an advanced way we will have to use the command line.

Completely virtualize the entire HW and SW infrastructure of a department of my company.

This allowed for hardware independence, resource consolidation and keeping up-to-date backups of all virtual resources.

Clean, clear web interface

Ability to do anything via command line

Can find any solution online, nothing behind paywalls or support contracts

Fast in all areas

Reliable, no crashes, no outages.

Full featured, not crippleware

Regular substantial upgrades

Nag screen at login, but hey, they put in a lot of resource, so I don't really mind.

Toss it on a spare server, the install is so next..next..next easy.

Give it a run with some test, development and non-production virtual servers

You'll be impressed with range of features, ease of use, scaleability.

As your skills and confidence with it grow, you'll soon be using it for more important loads.

Runs Windows virtual servers flawlessly, and certainly faster than running Windows bare metal on the same hardware. It caches disk better than Windows, so Windows responds quicker.

We've recently seen another company deploy it on 8 x hp dl380 g9's to carry 2 million mailboxes.

Small startup business needed two servers for file & application services.

Business has now grown to 50 people, and the Proxmox server has just kept up. More virtual servers added for specific applications. No slowdowns, performance is still exceptional. It can still easily saturate a 1Gbit network link and not be processor or ram overloaded.

Backups are reliable and easy to rollback.

We've now rolled out Proxmox to branch offices on micro server hardware, carrying the firewall & vpn, local caches, local infrastructure logging and local camera recording servers. Very efficient.

Overall benefits have been exceptional value, outstanding reliability, impressive scaling. The business has been able to depend on it's core servers, and get on with business.

I love Proxmox.

Its my stand out Opensource project over the last couple of years.

When I first took an interest it was purely for KVM as an alternative to Hyper-V.

But as I became more familiar with containers and Openvz I was sold as the management tools are awesome.

The web admin is great and links to Turnkey Linux add loads of value.

Config is tricky, Networking is a pain and upgrading is a nightmare if not managed properly.

Like a bomb could go off at any minute.

Do your research and make sure to properly design your architecture on paper before going live.

We have replaced our Hyper-V infrastructure completely and I now run Multiple could instances to handle web hosting and VPS.

Easy to use and manage many servers.

Clustered setup is quite easy to build.

Two virtualization methods, paravirtualzation (lxc or Openvz) and full virtualization.

Lots of storage methods.

Easy to debug when problems arrive.

Open Software model, free of charge.

Easy to move vps for one server to another, or even from one cluster to another.

Immaturity of some features like zfs.

Upgrade at your own risk (unless paid version).

Too expensive, if you want/need to use paid version.

Upgrade from major to major needs to be easier, with no downtime will be better.

Try on your own lab before going production. It's really easy to setup, but if you choose a bad combination of file system virtualization method... it will ruin your week.

If you are going to build a cluster, multiple nics is a must, don't even think of it if you don't have at least two networks (internal and external).

Give a try to externa storage, it will be easier to implement proxmox.

Backup system is nice and works great but if you use to recover single files or directories don't use it on qemu machines.

We have a not so big ISP, we are using Proxmox as part of our virtualization system.

It's open-source nature. Virtualization platforms can range in the thousands- it can also be deployed in a matter of minutes. This is crucial when IT departments are constantly being pressed to quickly deploy assets such as servers. Also, features like a web interface are a plus to avoid client installations that are often cumbersome to carry due to directory policies, deployment strategies, etc.

Promox’s control panel requires additional aspects such as historical usage, as opposed to current utilization. In addition, the console applet would improve by showing better definition boot screens along with a VNC activated by default. This would definitely improve user experience.

As with any virtualization product, planning your hardware is crucial. Although Proxmox runs on top of Debian, ensure you understand its limitations and other requirements such as back-end storage.

Reduce operating costs. Testing environments (VMs) are always being created as a result of sandboxing and other in-house security practices.

It is very easy to get started with Proxmox VE, in with the disc or USB-stick, follow some easy on-screen instructions and you have a virtualization environment that is very useful. If you want to build a cluster of machines you can do that as well at no additional cost, while other free virtualization platforms like VMWare ESXi reserve clustering functionality to paying customers only. Don't take me wrong, if you are building a business on that Proxmox will always be there for you then you should buy a support contract - but you don't *need* to do that.

Lack of API support from 3rd party. Proxmox VE isn't Citrix XenServer or VMWare vSphere, meaning that out of the box support from other tools or vendors are limited. Of course there is a well documented API so you can automate all the menial tasks, but there is not so much support from 3rd party products that takes advantage of Proxmox API.

Unless you have a requirement for 3rd party software to control and automate your Proxmox VE I can't recommend it enough. Unfortunately I had such requirements and it would take too much resources from the main objective to add support for Proxmox VE API then to switch to an already supported platform.

I was building a lab for malware analysis where free access to the components is a key design requirements because I want make sure that the results can be recreated by anyone on a very limited budget.

Price (free) is nice, but the stability and flexibility of the tools are the key. Have run Proxmox cluster for about 5 years now. They continuously improve the product. The capabilities of this product are great. Low footprint on older server hardware, am able to virtualize both windows and linux instances without a problem

So I have to pick something? Documentation. But truthfully, the user community makes up for any voids in their formal documentation.

Hosting multiple vms (phone system, 2 Windows servers, 4 Ubuntu instances) on an old PowerEdge Server -- what's not to like?

The software is based on Debian and works well on a wide hardware base, the software provides a really good simple to use and install.

The system does feel more cottage than enterprise, which while I like I can see others not liking.

While i'm sure the creators or Proxmox would probably disagree, this software works amazing on test platforms and situations with lower-end hardware however despite such amazing HA features and hardware support I do feel that for a larger enterprise this may not be suitable for the core virtualisation platform.

I was looking for a low overhead platform to base some HP Microservers on for a test infrastructure.

Initially using it to manage OpenVZ VE, we recently switch to LXC ones following recent change in the product. Proxmox provides us with improved control on our hosted VE and allow easy tuning and management. Pack with powerful features, it still allow simple management. Its integrated firewall, the command line tools, and the transparence of the solution are all contributing to our feeling of freedom.

The biggest improvement I would like to see is in the documentation. You currently have to read forums, faqs, books from third parties in order to really understand and be able to use Proxmox at its full power.

A good alternative to VMWare that allows lighter VE and therefore reduce the hardware cost for an equivalent performance, and without compromise on features.

We are hosting on-line application for our clients on Linux based computer. The ability to use lightweight containers, not full virtualisation, to manage them easily and also to secure helps limit our hosting cost and improve the quality of our service to customers.

It's a free dedicated virtual machine server with a nice GUI that uses standard technologies such as KVM and OpenVZ. It has good built-in features such as automatic backups & fail-over (HA). It has support for both local and remote disks (NFS, iSCSI etc). It's core is based on Debian, which vouch for stability. Everything is open-source and free, but for the one who wants customer service and access to enterprise repositories this can be purchased as well.

I don't really like the Java-based console to access the machines, mostly since I don't have Java installed on many of my machines. This has almost been a deal-breaker for me, but I've learned to live it, and Java is now easily installed on both Linux, Mac OS X and Windows.

Take you time to get to know the system before going live. There are many many good features as well as some quirks (such as the Java consol) one has go learn and get used to. All in all Proxmox is a great product for everyone looking to run both KVM and OpenVZ on the same machine, and administer it through a web-based GUI. It's all free, except for various service agreement you purchase for Proxmox.

WIth Proxmox I can run my own virtual machine park both at home and for my own businesses without paying lots and lots of money.

Containers. I've been using Proxmox for 8+ years because of this.

Long before containerization was a thing, long before Docker, Kubernetes and all buzzwords regarding containerization were a thing... it was Proxmox.

There are still features Proxmox support that some virtualization and containerization solutions are still lagging behind, like seamless node migration between machines with zero downtime, memory ballooning and user-space quotas by containers in a shared environment, for example. These features, that are now taking off in commercial solutions, were already present... 8 years ago!

Updating between versions can break things, and due to the nature of LXC containers, switching between kernels can be a pain.

Fortunately, the community is open and easy to interact to, so most issues are easily solvable.

Use distributed storage: Ceph or ZFS over NFS. If you want to benefit from live migrations between nodes of your containers and/or virtual machines, it is mandatory to use them. I know it can be a pain to configure, administer and check that everything works, but at the end it pays off. It's a joy when you have a hardware failure in one node, then you migrate everything to another node and just go a replace the failing hardware without you to worry about data, availability or downtime on your containers/virtual machines... I really recommend you this way,

Also, if you use ZFS, please buy a couple SSDs and add cache to it, as VMs can be really disk-demanding.

Microservices isolation, high availability, server sharding and multiple node resilience.

Web management

KVM and Containers.

Ease of use

Removal of OpenVZ.

Lack of clustering over WAN.

Proxmox is a great alternative to VMware and SolusVM. Highly Recommended

We were looking for a hypervisor for a small company however the costs involved in VMware were not worth while.

We now have a single server in the office rather than 4 and we can quickly setup extra VM's for development and testing purposes.

Easy to use interface, regular updates and stable interface

Better reports and Data analysis would be helpful

Managing virtualitation containers
