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

Pros
Scaling the solution is easy. You just have to add more hardware.Our production servers are running in Linux, and this solution supports that environment well.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.It is an open ecosystem, and we see there is a benefit in open-source solutions.I think nine out of the ten supercomputers in the world use Linux KVM, so I think that attests to the fact that it is a scalable product.KVM has a rich options set which can be directly used or via wrappers, such as libvirt.If you are a Linux desktop user, KVM is the solution to go with if you have to start virtual machines with Linux or other operating systems with almost zero extra configuration needed.

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.Proxmox allows us to achieve affordable performance while keeping high levels of data protection and flexibility.It is easier to balance loads across hypervisors if a given container or virtual machine uses more resources than its peers.We now have the ability to quickly build and deploy VM desktops for application testing with the snapshot ability to rollback, as required.Saves a lot of time compared to imaging physical desktops.The template option allows us to build a desktop in a VM, then quickly deploy as a linked clone.

Cons
The solution should be more user friendly. We are struggling with the command lines.Support for VF is needed, where you can, for example, export from VMware to KVM.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.We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide. A lifecycle component would be very beneficial.Technical support is not top-notch.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 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.It would be nice to have total CPU and RAM allocations show for all VMs/CTs to avoid overloading an individual hypervisor.Separate physical network for Corosync/Heartbeat should be emphasized in the Quick Start or Getting Started documentation.Some of the more advanced features and options required for setup still need to use the console and hand edit config files.

Pricing and Cost Advice
This solution came with the Linux license.It is cheaper than other solutions out there on the market.It is cheaper than other competitors like VMware or Hyper-V.​It is free and can be run from your laptop, if needed, unlike VMware.​

Proxmox is free software, but if you prefer the support and a more rested repository then you can pay for it.An excellent choice for budget sensitive operations.​The cost is excellent.
