What is most valuable?The GUI interface makes the management of KVM easier than ever before. The performance of this solution is great.
What needs improvement?This solution is lacking in features such as management and integration. * This solution needs better integration with desktop virtualization. * Better integration with storage solutions is needed. * Business continuity features need to be… more»
Which solution did I use previously and why did I switch?I have used XenServer and VMware, and the performance of KVM is better than these. When it comes to management, integration, business continuity, and live migration, KVM is lacking features and VMware is better in this area.
What other advice do I have?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… more»
Which other solutions did I evaluate?I evaluate options such as XenServer, VMware, and KVM every six months in order to choose the best product for my customers.

What is most valuable?I like that this is an open-source solution. It is very powerful, and it's easy. When you install Hypervisor with KVM, you can transform it into a server with the graphical QEME in minutes, then look at what you have and remove all… more»
What needs improvement?The virtual manager and the graphical QEMU for KVM need some improvement. In the next release, I would like to see some changes made to the dashboard as it would be nice to see some icons and some graphics when you are showing this solution… more»
What's my experience with pricing, setup cost, and licensing?This solution is an open-source, free platform with paid support.
Which solution did I use previously and why did I switch?I have been using VMware, ESXi, and Linux and will continue to use them while I get more experience with KVM.
What other advice do I have?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… more»

What is most valuable?KVM is a very good solution for the user ecosystem. The KVM service is well managed with a central policy interface.
What needs improvement?The initial setup of this solution is more difficult than some of the competing products and it could be improved. I would like to be able to see virtual networking integrated with the virtual machine.
Which solution did I use previously and why did I switch?We were using VMware prior to KVM. It is a very reliable and very strong solution, but it is also very expensive. We are switching to try and reducts cost both in terms of licensing and managing.
What other advice do I have?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… more»

What do you think of KVM?
What is our primary use case?My primary use case for KVM is running multiple VMs and containers on the one node.
What is most valuable?I find the density of the product most valuable. It is because of kernel same page merging technology (KSM) that is integrated into Linux kernel. That high density makes KVM one of the important players of the virtualization market.
What needs improvement?In the future release of KVM, I would like to have improved support for Windows guests.
For how long have I used the solution?More than five years.
What do I think about the stability of the solution?The stability of this solution is less than other products in the same category. But, it is OK.
What do I think about the scalability of the solution?The scalability of the product…

What is most valuable?A big strength with KVM is that it is an open-source component. It gets improvements from Intel, for example, and the other semiconductors. It can be sized-down to a very small package. It can be used in embedded systems as well, so it has a very good performance and it is suitable from embedded IT… more»
What needs improvement?I would like to see a separation, so you could have KVM running in a few cores, and then you could have a real-time operating system running another core, so there is a hybrid environment with real time operating systems and Linux.
What's my experience with pricing, setup cost, and licensing?It is cheaper than other competitors like VMware or Hyper-V.
Which other solutions did I evaluate?We compared KVM vs VMware and did a proof-of-concept, but we decided that KVM was best suited for our needs when it came to device drivers, etc. We also considered Oracle and RedHat.

What is most valuable?There is a lot of value with an open source solution because you have some freedom of changing how the system behaves and looks because it's open source. You can modify to your requirements which you cannot really do with VMware.
What needs improvement?The management of the whole system, could be improved. VMware is better on the management tools, for example, Red Hat is when it comes to the KVM. In addition, we would like to have a software lifecycle solution included in this solution… more»
What's my experience with pricing, setup cost, and licensing?It is cheaper than other solutions out there on the market.
Which solution did I use previously and why did I switch?We previously used VMware but switched to KVM because it is an open ecosystem and we see there is a benefit in open source solutions.
Which other solutions did I evaluate?We also evaluated Red Hat, SUSE, Canonical(Ubuntu), and other Linux providers.

What is most valuable?The solution is very light when you are putting your Operating System on it. You forget that there's a virtual layer on your solution. You are using it as if it was a whole computer. It's like having an entire computer that you've launched and have running with the Operating System that you need to work with.
What needs improvement?The solution should be more user friendly despite that some interesting graphical solutions are available to manage the VMs. it would be usefull that the solution integrate the VM snapshot features and make it graphical, so we have a VM infrastructure more complete and easy the backup/restore in case of issue.
What other advice do I have?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.

What do you think of KVM?
What is our primary use case?We are no longer using this solution. We evaluated it, but I have not used it in a production environment. This solution is used for virtualization. We have an on-premises deployment.
How has it helped my organization?same features that vmware have concerning disaster recovery, high availibility and live motion of vm
What is most valuable?simplicity of installation
What needs improvement?full interoprability with vm format (ova, ovf, ..) for been aable to move forward or backward to another virtualization solution
What do I think about the scalability of the solution?We did not test scalability during our evaluation.
Which solution did I use previously and why did I switch?We are currently using VMware in our production…

What is KVM?KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
