We performed a comparison between KVM and VMware ESXi based on real PeerSpot user reviews.
Find out in this report how the two Server Virtualization Software solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Documentation and problem-solving troubleshooting are the most valuable features. Performance (when fine-tuned and with "special" HW) is awesome, equal to or more than other enterprise closed-source solutions."
"The product is really good...One can get good performance because of kernel-based virtualization."
"The initial setup was very easy."
"The most helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so."
"Our production servers are running in Linux, and this solution supports that environment well."
"The tool's most valuable feature is backup. The product makes it easy to manage virtual machines. Other tools require third-party applications like VMware and vSphere. However, KVM doesn't require these applications."
"One of the best features of KVM is its user-friendly interface."
"I have found KVM to be scalable."
"My customers are satisfied with the solution’s performance."
"The product is very reliable."
"The speed is around thirty percent slower than another competitor. This would be something to work on."
"I have encountered difficulties in getting the tool's documentation."
"The networking with wireless devices needs improvement."
"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."
"The KVM tech support is really bad. They are not very responsive."
"I believe KVM offers a unified answer, while ProxMark addresses orchestration. KVM lacks orchestration. If the aim is to centrally oversee multiple KVMs – let's say to freeze them – a centralized management solution is absent."
"Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view."
"The main drawback in the solution is probably disaster recovery."
