We performed a comparison between KVM and Oracle VM based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the parameters we compared, KVM comes out ahead. It has the speed, stability, and flexibility that make it a very desirable solution for today’s rapidly-changing, ever-growing tech environment. This particular Oracle product, although very mature, has not done enough to stay competitive.
"The product is really good...One can get good performance because of kernel-based virtualization."
"Very cost-effective."
"Good screen and keyboard sharing feature."
"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."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"The key aspect is that the KVM directly interacts with the Kronos. There's no clear indication of indirect communication with Kronos. It is not linked to Kronos, and interaction is straightforward without any intermediaries."
"The most valuable feature of KVM is its stability."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"The solution is easy to use. You can spin one up when you need to and then shut it down."
"The most valuable features of Oracle VM are live migration and snapshots."
"It is simple and straightforward, and it will only require you one system integrator to do the job."
"The cloning is a great feature and live migration is very easy."
"I rate Oracle VM's scalability a ten out of ten."
"We've noticed that when working with Citrix with our Oracle clients who also use Oracle Linux, the monitoring and testing is simpler and easier for us to do."
"It provides enhancements for network and storage configuration, policy-based management for delivering application resource flexibility, and a GUI."
"It is very useful for the project management of our company."
"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."
"The stability of this solution is less than other products in the same category."
"The networking with wireless devices needs improvement."
"The main drawback in the solution is probably disaster recovery."
"Its resource usage can be improved."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"The solution’s user interface could be improved and made more user-friendly."
"Business continuity features need to be added."
"Oracle VM could provide integration with backup solutions."
"We do have a little trepidation with systemd, as it does have a learning curve."
"Something that could be improved are the snapshots that go in the ZFS Storage. If you want to enjoy Oracle VM, you will definitely want it to go together with ZFS Storage to maximize on the snapshot facility."
"Oracle VM should be promoted more as an open-source and stable software."
"I've found that using Oracle VM is like stepping back in time. It's not kept up with technology. The only reason anyone uses it is that they're afraid of Oracle's licensing. Oracle has a tremendously bad licensing approach."
"There is no memory over-subscription and CPU over-subscription. That has to be improved in terms of Oracle VM perspective. The other leading virtualizing software solutions have this feature."
"One is the hypervisor. Right now, it’s all using Xen. What would be really helpful is to have some choice, and the underlying hypervisor technology use KVM which is very popular with certain workloads."
"I think more Command-Line options for the product, for deployments."
KVM is ranked 4th in Server Virtualization Software with 39 reviews while Oracle VM is ranked 7th in Server Virtualization Software with 78 reviews. KVM is rated 8.0, while Oracle VM is rated 8.0. The top reviewer of KVM writes "Delivers good performance because of kernel-based virtualization". On the other hand, the top reviewer of Oracle VM writes "A cheap option available for Linux environments which is useful for many workloads". KVM is most compared with Proxmox VE, Oracle VM VirtualBox, Hyper-V, VMware vSphere and Nutanix AHV Virtualization, whereas Oracle VM is most compared with VMware vSphere, Oracle VM VirtualBox, Proxmox VE, Hyper-V and RHEV.
