Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"I find the density of the product most valuable. It is density that a technologist can just assign page merging. This is what makes KVM one of the important players of the virtualization market.""The initial setup was simple.""Our production servers are running in Linux, and this solution supports that environment well.""Scaling the solution is easy. You just have to add more hardware.""I like that this is an open-source solution. It is very powerful, and it's easy.""The GUI interface makes the management of KVM easier than ever before.""The KVM service is well managed with a central policy interface.""If you prefer command-line, there are all kinds of command-line options."

More KVM Pros »

"Proxmox allows us to achieve affordable performance while keeping high levels of data protection and flexibility.""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 most valuable feature of this solution is performance.""The solution allows for easy integrations.""The solution is easy to install. It can run on a lot of different types of hardware. Creating virtual machines with it is really easy.""The most valuable feature of this solution is migration.""The initial setup was really straightforward and easy.""Ease of use, HA, internal 100gbps Virtio network, built-in backup (don't pay $1200 Veeam licence), support for multi-monitors on multiple VMs in KVM, no need to RDP in the VMs to do your stuff (Win, Linux and Mac with SPICE and using 6 screens here (11520*2160)."

Cons
"The stability of this solution is less than other products in the same category.""The KVM tech support is really bad. They are not very responsive.""Support for VF is needed, where you can, for example, export from VMware to KVM.""The solution should be more user friendly. We are struggling with the command lines.""The virtual manager and the graphical QEMU for KVM need some improvement.""Business continuity features need to be added.""The initial setup of this solution is more difficult than some of the competing products and it 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."

More KVM Cons »

"This solution needs a more flexible and efficient backup solution in the dashboard.""The solution should include some features that can help with converting raw files into different formats. It should offer better management around raw files.""I would like to see more monitoring in the next release of this solution.""The solution needs a better billing system.""We had some challenges with management including volume and storage management. Setting it up properly and making it work, specifically shared storage between the virtual machines, is difficult.""If this solution could import directly from OVS format then it would make migration much easier.""The virtualization can be better.""The Windows drivers could be easier (unlike manually installing Ballon, QEMU and optionally SPICE, VIRTio, etc.)"

Pricing and Cost Advice
"This solution came with the Linux license.""This solution is an open-source, free platform with paid support.""It is free for everyone."

More KVM Pricing and Cost Advice »

"Proxmox is free software, but if you prefer the support and a more rested repository then you can pay for it.""Zero - this is a free solution.""The only thing you pay for is support and it is between $2,500 and $3,000 a year. It depends on the support plan you choose. Support is optional.""I am not aware of the licensing cost, but there is a cost for support.""It's an open-source solution that can be used free of cost."
