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.
"Cloning is the best feature in Oracle VM."
"The solution is easy to use. You can spin one up when you need to and then shut it down."
"Stability-wise, I rate the solution a ten out of ten."
"Overall, the biggest performance is around virtualization and automation, you can build private clouds with Oracle VM using Enterprise Manager."
"It provides enhancements for network and storage configuration, policy-based management for delivering application resource flexibility, and a GUI."
"I don't need to create a repository to allocate storage to my virtual machine, rather I can just use store locally."
"The solution is very stable. I don't recall any bugs or glitches. It's reliable. It doesn't crash or freeze."
"Its ease of management and simplicity are most valuable. It is free, and you can provision an unlimited number of VMs at no cost for clients. They also provide perfect support."
"VMware vSphere is a very stable product."
"Reduces downtime."
"We have seen an improvement in uptime. The whole hardware lifecycle process is easier."
"The most valuable feature is vSAN, as it reduces the cost of SAN storage and maintenance."
"It helps to automate the data replication and DR (disaster recovery)."
"Visibility: We can easily pull reports and give access to other people to look at specs or performance metrics."
"VMware vSphere is easy to scale. We haven't had any problems scaling what we're scaling now."
"I like the capability of logging into one system, then being able to shift over to another system within that single pane of glass."
"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."
"With our current OVM Manager version, migrating a VM from one repository to another repository was really complicated, especially editing and manually matching the configuration."
"I think more Command-Line options for the product, for deployments."
"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."
"I would say third-party plugins to other storage vendors. There are a lot of converged infrastructure setups; one that we have, multiple different hardware vendors. So that would be something we could definitely be looking for."
"An expanded data transfer option is one of the features I would like to have added."
"If there are issues with the storage, then all the machines go down, even if I have a backup solution in place."
"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."
"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."
"Technical support could be faster in terms of response times."
"They can lower the price of its license."
"There was a time we lost the password for the ESXi and we had to do a hardware reset. At this point, we had to fill up the ESXi from the bottom up. I am not sure if there was another solution to this problem but it took a long time."
"I would like to see VMware vSphere provide a centralized patch service on the VMware level, regardless of your operating systems."
"I would like to start to using NSX in the next release."
"The installation is complex and you need to have a good understanding in regards to what you are doing when you are setting it up."
"Lacks a simplified integration with services automation."
Oracle VM is ranked 7th in Server Virtualization Software with 78 reviews while VMware vSphere is ranked 2nd in Server Virtualization Software with 446 reviews. Oracle VM is rated 8.0, 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.

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.
