We performed a comparison between KVM, Oracle VM, and VMware vSphere based on real PeerSpot user reviews.
Find out what your peers are saying about Proxmox, VMware, Microsoft and others in Server Virtualization Software."The KVM service is well managed with a central policy interface."
"The GUI interface makes the management of KVM easier than ever before."
"Good screen and keyboard sharing feature."
"Very cost-effective."
"I think nine out of the ten supercomputers in the world use Linux KVM, so I think that attests to the fact that it is a scalable product."
"If you are a Linux desktop user, KVM is the solution to go with if you have to start virtual machines with Linux or other operating systems with almost zero extra configuration needed."
"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."
"This solution is open source and easy to configure."
"The solution is very stable. I don't recall any bugs or glitches. It's reliable. It doesn't crash or freeze."
"It is highly esteemed for its ability to efficiently optimize and enhance the operational speed and responsiveness of virtualized environments."
"Oracle VM is user-friendly and facilitates compliance with Oracle Licensing, a feature not provided by competitors like VMware or Hyper-V. Oracle prefers customers to use their technology. It is also easy to implement, clone, and deploy machines with Oracle VM, making it a convenient solution."
"There's a lot of space to customize the solution if you need to."
"It's a very mature product."
"The virtualization product Oracle puts out just complements the performance of the database."
"Virtualization platform that's easy to set up, and has good scalability and stability."
"Good visualization hypervisor."
"We have seen an improvement in uptime. The whole hardware lifecycle process is easier."
"We don't have any downtime because it was built right."
"The virtualization is set by itself. vSphere is the best way to have a non-host based fixed solution. We always try to find an agnostic environment where we can restore agnostics or just say, "I need resources, capacity." That's why VMware vSphere in particular, has been the best in the past but now also with the evolution of their product. Nowadays, you don't have to use any STEM infrastructure anymore because the bandwidth and the land speeds are getting steeper."
"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."
"VMware vSphere has useful tools for management and support."
"I like that it's like a distributed rescheduler. You can move to and use VMotion as well. You can move the server and move the virtual machines around different physical servers. This makes it easier when it comes to redundancy."
"Most valuable features of vSphere 6.7, for us, at the management level would be: VCHA is a nice redundancy feature that they added in v6.7. I like the quality of life improvements with the VMFS-6 for using auto UNMAP on the data stores. And we really appreciate the improvements to the Clarity UI where we can manage Update Manager (VUM) and our vSAN stack within the modern interface."
"The stability of the solution is excellent."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"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 solution’s user interface could be improved and made more user-friendly."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"The main drawback in the solution is probably disaster recovery."
"Monitoring and resolution could be improved."
"The virtual manager and the graphical QEMU for KVM need some improvement."
"Its resource usage can be improved."
"Deployment should be simplified."
"Oracle's VM VirtualBox is a powerful, free, and open-source virtualization tool. However, you'll have to read a lot of documents and perform experiments in test environments to make it work for you."
"The performance could be better because I need to purchase a lot of CPUs to perform in the workbench."
"We do have a little trepidation with systemd, as it does have a learning curve."
"An expanded data transfer option is one of the features I would like to have added."
"The only improvement needed for Oracle VM is the look and feel of the interface."
"You need to have a model for documentation available for the users. Right now, if you have to search for some troubleshooting, you need to have Oracle login. Many personnel might not have that login. The reach, the availability of information to the end-user, is not there."
"The solution is at its end of life and is about to be discontinued."
"Its price can be better. It is very expensive."
"The biggest pain point is probably the firmware management of the underlying hardware. It could be a lot better."
"I know VMWare has this Operations Manager. I know that it comes at a price because VMWare normally wants to charge for everything in the software. But I'm not seeing all the features of the Operations Manager. I only see a few features. If all the features can be included in one package, that would be good."
"The HR proxy is actually a little bit tricky to install and setup."
"The management of the product demonstration is weak."
"We've been using vSphere on Windows 7, and it had less fluff associated with ThinApp. Currently, with Windows 10 version that we have, it adds a lot of bulk to ThinApp. We have offices spanning across Canada from the east coast to the west coast. A ThinApp that is roughly around 400 MB in size would take minutes to open up. With Windows 7, the same ThinApp used to be close to 75 to 80 MB in size. So, I'm really not happy with the extra fluff that is bundled in Windows 10. It really messes things up for us at times."
"The initial setup is a bit complex."
"One problem that needs fixing is when we run the backup for the servers, the servers become inaccessible to everybody on-site while it is creating a snapshot."
