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.
"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."
"Good screen and keyboard sharing feature."
"The GUI interface makes the management of KVM easier than ever before."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"If you prefer command-line, there are all kinds of command-line options."
"I have found KVM to be scalable."
"KVM is stable."
"Proxmox is free, very stable, and doesn't require more resources for memory RAM. It's fine for a small data center."
"The most valuable feature is the ease of deployment."
"It is easy to deploy."
"That the product is free and still has all the features you expect is a huge benefit."
"The affordability of the solution is the product's most valuable aspect."
"The virtualization is good."
"It fits in well with our organization. It works and does what it says it does."
"Proxmox VE is simple to use and it is feature rich. The fact is that it performs,"
"There are some issues with the graphics and some software that is very complex."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"Business continuity features need to be added."
"Monitoring and resolution could be improved."
"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines."
"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."
"Its resource usage can be improved."
"In our setup, we do not have any dashboards or orchestration, and it is hard to manage. We have 25 gig network cards, but the software driver we have only supported 10 gigs."
"A feature which should be added is the ability to encrypt the main installation."
"The only issue I have with Proxmox VE is updating it. You have to manually update it or you have to have a way to update it automatically."
"Its user interface can be improved. In the version that I am using, not all functions can be performed by using the UI. There can be some improvement on that. I'm assuming that it has already been improved in the latest version."
"It's one of those things for me to move things on to the cloud. It's not so easy. I am always on the laptop and have to monitor that because if you want to make strides; you need to stay online."
"The initial setup has a pretty steep learning curve."
"There are some things that need to be done using the command-line interface, and these should be moved into the web-based interface."
"The availability of the solution could be a bit better."
"Backup and recovery could be better. It's a bit problematic. If you're not well-versed with Linux, it tends to be a bit of a challenge when setting up and recovering. It's not really GUI-based, and if you're not a good Linux user, it becomes a bit difficult. In the next release, I would like to have something like Hyper-V's Data Protection Manager, where you could do an offsite backup and keep a copy. I haven't seen that incorporated yet, but I'm sure they will do that."
Proxmox VE is a complete virtualization management solution for servers. It is a powerful open-source platform and supports two virtualization technologies - KVM (Kernel-based Virtual Machine) for virtual machines and LXC for containers. Proxmox VE has a central user interface that allows you to manage not only VMs and containers, but also storage resources, network configuration, and high availability for clusters. It is enterprise-ready and is valued for its scalability and maximum flexibility, enabling you to virtualize very demanding workloads. Proxmox VE makes it possible for you to easily install, manage, and monitor hyper-converged (HCI) data centers.
