We performed a comparison between Oracle VM and VMware VSphere based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the parameters we compared, VMware VSphere got better user reviews. One major difference between the two solutions is that users say VMware VSphere is more user-friendly than Oracle VM.
"Good visualization hypervisor."
"The solution is very stable. I don't recall any bugs or glitches. It's reliable. It doesn't crash or freeze."
"What I like best about this product is that it's free."
"The most valuable aspect of the solution is the resource management from the OVM Manager."
"The biggest advantage of Oracle VM is that you can separate your clusters to get your licenses agreement in scope."
"The Foundation is the most valuable feature of Oracle VM."
"I rate Oracle VM's scalability a ten out of ten."
"What I like the most is the failover and the quick restore of virtual machines."
"It is the number one virtualization-layer platform available, and a lot of people trust it."
"It has allowed us to be more resilient to infrastructure and hardware failure, reduced hardware costs, and decreased recovery time from failures."
"We could easily move workloads from on-premises to the cloud and vice versa if we were running on-premises and cloud, which is one of the most important points in the new releases, in particular."
"The most valuable features for me are a very easily scalable infrastructure. I can have a couple of hosts to do basic workloads. I can have a lot of hosts to do a lot of workloads. vSAN integrates my storage so I don't need an external storage SAN. I love having everything integrated in the same UI. The new HTML5 interface doesn't require any plugins anymore and it's super-fast."
"vMotion is one of the most useful features, which helps to provide both flexibility and High Availability. With new versions of vSphere and vCenter, it is still improving (e.g., vMotion across vCenter Servers and virtual switches)."
"As an end-user, I would say it has allowed us to have the flexibility of moving around our workloads on different machines, and not having to worry if anything is down."
"The ease of movement of these machines is the most valuable. It is very easy to move these machines between physical hosts. The fast deployment of services is another valuable feature."
"It is highly scalable. We can add new hardware and expand the infrastructure easily."
"I think more Command-Line options for the product, for deployments."
"The usage could be easier, and more user-friendly."
"Its database management features could be better."
"If there are issues with the storage, then all the machines go down, even if I have a backup solution in place."
"Deployment should be simplified."
"The management can be improved more, and become more agile. It would be nice for it to become more rich in terms of UI. In addition, the replication to disaster recovery needs improvement."
"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."
"Incorporating analytics related to performance, particularly within the dashboard interface, would be beneficial."
"Sentencing has changed a lot."
"There are some limitations with the solution regarding migrating."
"Sometimes it's impossible to prevent problems from happening. With vSphere, you never know where the problem is going to come from, but you will always know that there is a problem. This is the problem."
"The hardware cost is high."
"The support for VMware vSphere can be fast or it can be slow. Recently it has been slow, they need to decrease the wait time and quality of their support."
"The price could be better. The licensing is definitely expensive and tech support is sometimes frustrating."
"In addition, I think some of the backup features or the prediction features can be improved."
"Two improvements that I would like to see are higher resolution console modes for guests and easier switching between consoles."
Oracle VM is ranked 7th in Server Virtualization Software with 76 reviews while VMware vSphere is ranked 2nd in Server Virtualization Software with 446 reviews. Oracle VM is rated 7.8, while VMware vSphere is rated 8.8. The top reviewer of Oracle VM writes "A cheap option available for Linux environments which is useful for many workloads". On the other hand, the top reviewer of VMware vSphere writes "Offers good performance and is useful for banking systems". Oracle VM is most compared with KVM, Oracle VM VirtualBox, Proxmox VE, Hyper-V and RHEV, whereas VMware vSphere is most compared with Hyper-V, Proxmox VE, VMware Workstation, KVM and Nutanix AHV Virtualization.

We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
VMware VSphere is better than Oracle VM because on Oracle Virtual machine migration is not an easy task as in VSphere due to complications existing in Oracle VM.
Also, Oracle VM is limited in features compared to VMware.
Oracle VM is limited also in communicating with other virtualization platforms like VMware.
If you need performance then Oracle OVM is more reliable.
Otherwise, VMWare is good enough. We are using 4 virtualization platforms in the production, development and test environments.
Technically, Oracle OVM is the best for Oracle products apps/databases. VMware is for Linux guest OS.
And hyper-v is for a Windows guest OS but hyper-v lacks network security and configuration.
Oracle VM seems to me to be kind of outdated. Nevertheless, it is fairly straightforward to use and maintain. The solution can just be set and you can forget about it, and the scalability is considered to be quite good. Oracle VM’s customer service and technical support are really outstanding. With this solution, you have the ability to patch with no downtime. Oracle has been around for a long time. It is complete in terms of its features, functionalities, and sophistication. It may provide good documentation and be easy to set up, but it has a terrible licensing structure. Oracle VM may help a company manage its costs, but that can come at another expense for a company - you have to work with an antiquated system.
VMware VSphere is fairly priced. Like Oracle VM, it provides near-zero downtime services. I think the way information is monitored needs to be improved. I feel like they need to have a better solution for hybrid clouds and migration to the cloud. It would also be nice to have additional integration options with different solutions at the application level (for example, Kubernetes). One of the biggest issues I have with it, is the firmware management of the underlying hardware. For firmware upgrades, for example, you have to take down your entire system. Even though it makes it easy to create virtual machines, it could be more user-friendly. In addition, the customer service and technical support seem to be average, but nothing spectacular. Overall, I would say that VMware VSphere is pretty stable and implementation is fairly easy.
Conclusion:
I’m not overly thrilled about either solution, but having had experience with both, I think VMware VSphere is better because it is easy to scale, pretty easy to use, easy to maintain and is mostly stable. And also, while Oracle VM may be more well known, I am not willing to work with an outdated product, especially since there are multiple other modern solutions available.
