Proxmox VE Reviews

Proxmox creates an environment for writing script and virtualizing. I'm the senior finance administrator and I work in a research department in the health arena. 

The product is cost-effective to virtualize because of the ability to always create VMs. It allows us to create an individual virtual machine along with the GPU for machine learning. We can create multiple NPI notes, and whenever they need it, we can just power some down and bring them out. The solution is open source which is great for us and it's very reliable. Proxmox has given us the ability to do what a commercial organization can do but it's free. You don't have to buy any hardware. If you do take a subscription, they provide support. It's a good model.

The process for deployment is complicated and can be quite difficult for some; there's a steep learning curve if you've never dealt with the product before. 

We've used this solution for a couple of years. 

Stability is good, the solution functions well. 

Scalability is good, we have around 100 users. 

The initial setup is easy for me, because I'm very familiar with this product. Deployment takes an hour or two. 

The subscription version is not expensive but we don't always have the money to pay it. In that respect, both Netgear and Proxmox have been very important to us. 

This solution is accessible to anyone. It does take time to learn and experiment with it. I rate this product nine out of 10. 

The primary use case for Proxmox VE is virtualization for a company and migration of some clients to Proxmox. We implement virtual machines.

For my customer, it's too early to say that, but we hope they are satisfied with it. For our strategy in the interim, we are looking to promote this product in the future.

The web page, the dashboard, and the ease of use are most valuable. The documentation and the community support are also very helpful.

For now, it’s too early to determine what needs improvement as it's only been three months. I don't have enough experience to say what can be improved.

I have used the solution for three months.

Proxmox VE is stable. At the beginning, there were some minor issues, but they were easily resolved.

I have not tried to scale it yet.

The initial setup was straightforward. It took only one day to deploy. Clear documentation made the process smooth.

During the initial setup, I just followed instructions from my manager.

The pricing is very competitive. Proxmox VE is more affordable than its competitors, such as VMware.

I researched Amazon, Azure, IBM Watson, and others.

Please read the official documentation thoroughly. It is comprehensive and very useful.

I'd rate the solution seven out of ten.

I can enter Proxmox VE on VPN. Proxmox VE is very lightweight, and it doesn't take a lot of memory on the device. I can import OVA files inside Proxmox VE. I love Proxmox VE's backup, which is very, very powerful. Also, we can directly install a container inside Proxmox VE.

Since I face issues importing Windows OVA inside Proxmox VE, a clickable button should be added to select the OVA format and import it inside Proxmox VE. It would also be beneficial to view the import and import of the VM inside Proxmox VE.

I have been using Proxmox VE for three years.

Proxmox VE is a stable solution. I rate Proxmox VE a seven out of ten for stability.

Two people are using Proxmox VE on my site.

Before Proxmox VE, I used VMware. I switched to Proxmox VE because I love Linux. I can install online logs and automate some stuff on Proxmox VE. Also, people recommended I use Proxmox VE.

Since I do not deploy Proxmox VE in a production environment, I do the installation and maintenance myself.

I cannot subscribe to Proxmox VE's support because it is expensive.

I am using the latest version of Proxmox VE. Proxmox VE is a very, very good solution with good features.

It would be good if you could make a cloud image of Proxmox VE for Amazon, Azure, or Google.

Overall, I rate Proxmox VE an eight out of ten.

The ability to back up a host and keep it running is valuable. For a free solution, it provides plenty of features that we find on VWware. We can test networks with the solution. We cannot do these tasks on consumer-grade virtualization services like Openbox or Windows Hyper-V. I found the documentation pretty complete. I was able to find pretty much everything.

It is difficult to remove a virtual machine. Also, it should be easier to find what we remove.

I have been using the solution for three months.

The solution is stable. I rate the stability a ten out of ten.

The initial setup was straightforward and pretty easy. It took us an hour to deploy the first VM. It was pretty fast.

The solution does not require any maintenance yet.

The tool is free.

I just started to configure the product. I will set up the second server next week, so I’ll see how scalable the solution is. I do not know it yet. I didn’t have time to use the full solution to see what could be improved. Overall, I rate the product a ten out of ten.

Proxmox VE is used for many sectors, such as medical, IT, and electronics. It is an open-source server management platform.

The most valuable features of Proxmox VE are the ease of containerization. Overall the solution is generic, feature-rich, and has compatibility.

The documentation in Proxmox VE could improve.

I'm new to this type of solution, there are all these features and options to select in various scenarios, but there's not much documentation out there to explain which option you should be choosing for what, and why. I know there are a lot of YouTube articles, Reddit documentation, and other information where people say if you want to do task A, here's is how, and people follow it blindly. However, nobody understands what they're doing, and why.  I'll tackle any task and develop a solution but I need to understand what I'm doing. I need to understand why I'm selecting certain options, what makes that appropriate, what would make the other option inappropriate, the pros and cons, the whole run-through. I find the documentation lacking.

What I have noticed while I'm running a firewall, FireHOL, which works with DNS, and a media server all runs on my Gen 8 MicroServer. It's an I3350 with 10 gigs of RAM, and I do find that the RAM usage is pretty high. I know I do not have all the RAM allocated to the containers, but I find that the overheads there seem to be pretty high. The high RAM usage comes with input-output latency. I don't seem to have the same problem on the dual Xeon, but again that has infinitesimally more computational power, one would expect that to run quicker.

When it comes to the firewall and other aspects, I'm only looking for a simple solution, low power consumption, good performance at home, to keep my home network on. If the documentation went into a bit more detail on what the overhead requirements of Proxmox VX are and why, and how to optimize, especially when you start bringing in Oracle ZFS and VFS power systems. The RAM usage increases a lot. There's practically nothing about that in the documentation. You have to hunt down the details in VFS, and its functionality elsewhere to figure it out.

On the dual Xeon, for distributed computing, it is running fine. The system is running 24/7 without any problems.

At the moment, one of the limitations is hardware passthrough into containers. To do that, you have to start getting privileged containers. I know there's a lot of hype in the public domain as to the pros and cons of that, and some parts are supported and some are not. It would be interesting to see if technology could develop to the point where we could pass through hardware into containerized applications.

I have been using Proxmox VE for approximately one year.

Proxmox VE is stable and reliable.

Server stability's been phenomenal and I'm running it on several old HP MicroServers. They're Gen 7, using the AMD Turion chips. I've been running it on the Gen 8, I3, 350, and dual CPU E3 in Xeon. there are some performance differences based on what the hardware's capable of, but no matter what platform I run it on there has not ever been any stability problems whatsoever.

The scalability is good. If you're working with generic processor models, it's easy to shift them across different platforms once you place the CPUs.

I have not needed to use the support from Proxmox VE. I have found all the answers I have needed online from user groups and Wiki support pages.

I rate the documentation and community support from Proxmox VE a three out of five.

I have used previously VMware and VirtualBox. Both are installs that have been on Microsoft Windows, and I found them both to be very limiting, very difficult to set up and manage. Proxmox VE, I found to be the easiest to use, quickest in terms of response, and has the best functionality.

The initial setup is very easy. Once you get the hang of it, setting up the VMs, containers, and deploying them is incredibly quick.

The setup for most of the configurations is similar, once you understand the concepts and the principles, it comes down to basics. You know your hardware and what you're setting up, and what it's capable of doing. You can't set up older generation hardware and then expect to have PCI Express Passthrough or GPU Passthrough, because the hardware doesn't support it.

You can't expect the solution to do what the base hardware is not capable of doing. Work within the constraints of the hardware, understand your hardware, and the OS.

You can download the solution and it is an open-source installation, it is exactly the same as their commercial solution.

The maintenance of the solution depends on how you've set it up. If you've only set it up as a functional hypervisor, you have your VMs running, and that's the last thing you did, then you're going to have to come back every two weeks or every month to check on your OS updates, upgrades, and security patches, et cetera. However, you can automate a lot of that with Cron jobs. It's about learning the system which is based on Debian. If you understand Linux and Debian, you will understand how powerful the system is and what you can actually do with it. When you start running things, such as Monits or syslogs, you can automate any error messaging or any problems and it can be sent to your system administrator in an email.

Whether it's a case of regular backups that are happening, if everything is working well, then great, but if one fails, an I/O error or other errors pop up and you get notified of it quickly, then you can fix it easily. If you're only coming in every four weeks to have a look at it and see what's going on, things could have gone horribly wrong.

I would suggest to anybody who's running a hypervisor, is schedule regular backups. Back up your VMs regularly. Schedule it. Automate it, and make sure it happens on a separate machine, onto a separate machine, onto a separate host- because you don't want to lose your VM with all its backups.

If you've taken the time to set it up well with all your Cron jobs and automation, there will be almost zero maintenance.

I rate the implementation of Proxmox VE a five out of five.

To use Proxmox VE there is not a license required. However, you can purchase a support license, which you access, but it doesn't change the functionality of the solution.

Their licensing is very similar to other solutions, such as Canonical and Ubuntu. The full OS is available to you. If you want the support, you will need to pay a license fee.

My advice to others wanting to implement this solution is if you're looking to virtualize, ask yourself why. In terms of bringing your costs and energy consumption down, never mind the whole global eco-footprint hype that everybody wants to get onto. The reality is, for any business, keeping a business afloat is about dollars and cents, and if you can accomplish your IT tasks at a lower cost and expense, have better utilization of hardware, you've probably already hacked a path to what way to move forward.

Instead of spending hundreds of thousands on multiple servers, to then have a less than 5% utilization on each machine, while they using up 500, 600 watts of power, is not efficient. With virtualization, you're running multiple VMs on one physical piece of hardware. You get much better utilization out of it, you're getting much more for the money you are paying, and without any significant drop in performance.

When one considers the internal networking on the VM, where you have different VMs and your containers are running on internal networks. You're not limited to gigabits or 10-gigabits throughputs. It runs on the PCI Express speeds on the board, it is a lot quicker.

I rate Proxmox VE an eight out of ten.

This is a free version of VMware and that's why we're using it. It does everything that VMware can do and it's more flexible. We were looking for a virtual solution and we're a startup, so the cheapest is best. We are customers of Proxmox and I'm the technology operations manager. 

The feature I like best about this product is the fact that they have independent nodes. Proxmox is based on KVM and essentially you could lose a node. All the hosts that are running are evacuated elsewhere in the cluster and away you go. I have reduced infrastructure and I'm familiar with it because at the heart of the hypervisor is Debian Linux and I'm a Linux administrator. It didn't require learning a whole new platform and it's so easy to use. Proxmox will be in my toolbox forever, I love it.

This is a really great solution and the more VMware raises their costs, the more appealing it is. I'd be very nervous if I were one of the big companies because you're going to have administrators like myself discovering Proxmox and the cost is zero. With this solution, when something goes wrong, you Google it, you figure out the problem and fix it. Of course if you're an enterprise company, that's something else.

The product should have more enterprise features, perhaps DRS. I don't think Proxmox has the ability to sense that a host is running hot and needs to be evacuated. So DRS, dynamic resource scheduling, is a feature that constantly monitors the host and if it sees a particular host taking up a lot of resources, it will take that host off and throw it on a different host in the cluster that's not running as hot and doesn't have as much utilization. It protects the overall cluster 

As above, I think the DRS would be a helpful additional feature.

I've been using this solution for six months. 

As long as you're monitoring your host yourself, it's a stable solution. 

I can't really speak to the scalability. I haven't looked into it yet. We're a very small company and we have about five people using the solution, all at the director or senior level. We have a senior application developer, and a director level manager who brought the product in.

Does a three and a half minute setup sound reasonable to you? When I first installed it, I thought there must be more to it. I downloaded the ISO onto a thumb drive and made it bootable. Then you boot the server, boot off the thumb drive. You have to answer about six questions and that's it. Very simple. 

My only recommendation to anyone thinking of implementing this solution is to read up on it, but give it some serious consideration because it really is a great product. In other words, don't let the freeware label scare you off.

I would rate this solution a seven out of 10. 

The tool has very good performance.

The solution needs to improve its stability.

I have been using the solution for one month.

I would rate the tool’s stability a nine out of ten.

The tool’s setup is easy. The setup took two weeks to complete.

I would rate the solution a ten out of ten.

We use the open-source version of Proxmox for automation and other uses, including LXC containers. We use it for my enterprise applications and to offer our hosted cloud-services.

Proxmox with Ceph Storage as HCI has given really peace of mind to Management & IT for regular hardware maintenance, with near to zero downtime or no downtime for most of VM & LXC container keeping in mind service running round-the-clock for customer.

The feature that I have found most valuable is that its storage ZFS & Ceph, container based on LXC and everything else works out of the box. Additionally, it is a really stable, reliable, and scalable solution.

They have a good road map already in place, so I don't think there are any immediate challenges.

I don't have any real challenges about improvement here. (As most IT required features are included and they do have roadmap). Plus API & Command tool is lot helpful.

I personally keep exploring other players and backup/Restore/DR software.

And believe more advance features of backup/restore & DR Data Sync for Ceph  on GUI fronted would be added benefits for users coming from other platform.

On Security/Firewall/Software-Defined-Switch with more advance feature on webGUI would be also more helpful too.

I have been using Proxmox VE for more than six years.

Proxmox VE is an enterprise solution, it is used daily. Its regular maintenance is normal, the way you would maintain any normal infrastructure. There is nothing special or complex with it. We have a team of five people who maintain it, but there aren't any complex challenges.

My company is very small but I have more than 10,000 users accessing on ProxmoxVE Cluster. We provide the solution to other customers.

The thing about this solution is that is so stable I hardly need any technical support.

We used Raw Linux Virt-manger for per Server management for VM & LXC before, without any central management.

Everything has a learning curve, steps to watch, understand and explore. But with Proxmox there are hardly any challenges. I don't think the deployment took more than an hour.

Its was inhouse.

License & Support-subscription & running maintenance cost is bear minimum compare to other closed source solutions. We were able to use our other existing commodity server part of this cluster.

Recently, I have been a Proxmox reseller. I wanted to promote it in India because there is no reseller here. We are trying to promote Proxmox here because being open source it's not popular worldwide, although we have been using it in production for the last more than five or six years. We have been exploring Proxmox for small applications for more than seven, eight years.

Tried Xen, but was not comfortable.

With Proxmox VE you get everything in one box, including the ZFS & Ceph storage & LXC container technology. 

Even the support subscription is really good.

It's a wonderful open-source solution. It's out-of-the-box and it is easy to learn compared to other vendors. It is easy to deploy and maintain and you hardly have any trouble or challenges from the software. 

It provides peace of mind for management.

On a scale from one to ten, I would rate Proxmox VE a nine.
