If you were talking to someone whose organization is considering KVM, what would you say?
How would you rate it and why? Any other tips or advice?
The most important thing for people to do when they are researching this kind of solution is to try and understand the main reason and concerns behind virtualization. They should learn the strong points and weakness of this technology, and try to have a base knowledge to understand the concept and how it can be used and managed on a daily basis. I would rate this solution a seven out of ten.
I have been using this solution since before it was owned by Red Hat, when it was community-based. It is easier to manage than ever before because you used to have to use the command-line interface, instead of the GUI. I do not recommend this product for those looking for a stable and scalable virtualization solution because they will ultimately have problems in their data center. Just two weeks ago, I helped a friend of mine to migrate from KVM to VMware. I think that if Red Hat worked on some business continuity features and add them to KVM then it would receive a better grade and be a more competitive solution. I would rate this solution a five out of ten.
You can virtualize anything now, but in my experience, they are good for Linux and Unix systems. I have also used Windows. Even if you are using another platform hypervisor, as I do with VMware, you may get yourself in a situation where you want to install the KVM or at least the key tools. You can access RAM drives, or broken virtual hard drives, or migrate them to another type of hard drive. KVM is very complete, it is very powerful, but people are used to graphical QEMU and that is an issue. The solution performs well and has many tools. It offers everything that all other paid versions have. Everything is in your hands, all you need is the internet to access all of the information on KVM. I would rate this solution a nine out of ten.
We're using the on-premises deployment model. We're using the community version of the solution. I'd rate the solution nine out of ten.
