We performed a comparison between KVM and Proxmox VE based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the parameters we compared, KVM and Proxmox VE had a similar user rating regarding ease of deployment, pricing, and service and support. When it came to features, reviewers felt KVM was complex and not scalable, while users of Proxmox VE were unhappy that certain processes weren’t automatic, and moving things to the cloud was difficult.
"Documentation and problem-solving troubleshooting are the most valuable features. Performance (when fine-tuned and with "special" HW) is awesome, equal to or more than other enterprise closed-source solutions."
"The KVM service is well managed with a central policy interface."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"I have found KVM to be scalable."
"The initial setup was simple."
"Good screen and keyboard sharing feature."
"I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"The ability to back up a host and keep it running is valuable."
"Proxmox VE is very lightweight, and it doesn't take a lot of memory on the device."
"The solution's compatibility is very good with multiple operating systems. The moving systems are very good and migration is excellent. These are the most valuable features for us."
"The solution has good high availability."
"The most valuable feature is the ease of deployment."
"The initial setup was really straightforward and easy."
"Less infrastructure required; simple to use."
"The solution is extremely scalable."
"The only negative aspect of needing hardware support is a fully functional KVM can be dropped. It would be nice if the support for other platforms, like ARM or Risk, were as good as the x86 one. However, with the democratization of Chromebooks based on these chips and mobile devices, it will not take long for that to happen."
"The KVM tech support is really bad. They are not very responsive."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"KVM is very difficult to manage and run on daily operations."
"We are not getting good support from KVM, and it is not that user-friendly."
"One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy."
"The networking with wireless devices needs improvement."
"I have previously used VMware and KVM is easier to use. However, they both have their strengths depending on their use cases. They are mostly equal. One of VMware's advantages is it has better support."
"It is difficult to remove a virtual machine."
"There should be a helm feature for managing Kubernetes ports directly from the Proxmox traffic interface."
"It might be interesting to have the ability to integrate with other cloud solutions."
"If this solution could import directly from OVS format then it would make migration much easier."
"Proxmox VE can improve by importing OVF or OVA files directly from OVA. I need to convert all the images to raw images before importing them to Proxmox VE. If there is a solution that I can import directly from VMDK, it would be better."
"We have only command lines for a management application to remove sites. The solution needs a proper GUI."
"The solution should include some features that can help with converting raw files into different formats. It should offer better management around raw files."
"This solution needs a more flexible and efficient backup solution in the dashboard."
KVM is ranked 4th in Server Virtualization Software with 39 reviews while Proxmox VE is ranked 1st in Server Virtualization Software with 58 reviews. KVM is rated 8.0, while Proxmox VE is rated 8.6. The top reviewer of KVM writes "Delivers good performance because of kernel-based virtualization". On the other hand, the top reviewer of Proxmox VE writes "Easy to use and supports multi-monitors on multiple VMs in KVM". KVM is most compared with Oracle VM VirtualBox, Hyper-V, VMware vSphere, VMware Workstation and Oracle VM, whereas Proxmox VE is most compared with VMware vSphere, Oracle VM VirtualBox, Nutanix AHV Virtualization, Hyper-V and Citrix Hypervisor.

I use Proxmox VE and have been very happy with it. In my opinion, it is a complete and stable solution with excellent tools for managing servers. It has a lot of different features, and I also love the user interface. Setup is easy, it is very stable, scales well, and is a great fit that is suitable for my organization. Besides those advantages, another huge plus for me is that it doesn’t require any additional resources for memory RAM and it has independent nodes. I also chose Proxmox VE because it allows me to run services without needing dedicated hardware. With all that in mind, there are still some downsides to the product. Because it is still a very young solution, it sometimes has bugs. In addition, some processes need to be completed manually by command line because not all processes are automatic. And in the future, I hope they will add application storage.
KVM is easy to set up, deploy, and use. I think its ability to scale could be improved, though. If your organization relies on command lines a lot, KVM has several different command line options to choose from. From the information I have gathered from other users, KVM seems to have good customer service and technical support. In addition, the GUI interface is solid. In general, KVM seems like it performs well but it lacks good management features and needs to offer more integration options. However, in comparison to other solutions,KVM has a reputation for being faster. And while it provides a good screen sharing feature, the resolution isn’t great. Even though KVM is cost-effective, I think it lacks high availability across clusters.
Conclusion: Ultimately I chose Proxmox VE because it was a better option for my particular needs.
In a marketing services-related company security is paramount.
Therefore, you probably will rely on services, especially during maintenance of your network and need support for that.
When it comes to security and support KVM would be the better option. With in-house engineers, both Proxmox VE and KVM could be chosen. But qualified engineers are hard to come by nowadays, depending on where you live.
As a side note, I maintain mainly Xenserver, VMware and KVM. When it comes to performance per watt Xenserver would be the king, especially on larger setups.
Since your setup is of medium size and if you decided not to go for the aforementioned setups, KVM would be the lesser of the worse.
Your question depends a lot on the hardware/cloud system you have in mind. More details would make my recommendations more precise.
Kind regards,
KVM is a kernel base hypervisor while Proxmox VE is open-source. Technically, Proxmox VE fulfills the smallest business users than KVM.
And if we go for the quality and support KVM is better.
But Proxmox VE has also more features according to business growth.
