We performed a comparison between Hyper-V, KVM, and Oracle VM based on real PeerSpot user reviews.
Find out what your peers are saying about Proxmox, VMware, Microsoft and others in Server Virtualization Software."I like that Hyper-V comes for free with Windows Server. You don't need to buy the license, and you only have to pay for the management aspect in System Center."
"The organization has realized the benefits on smaller data center space, power, cooling, etc. apart from the benefit that the virtualization layer brings in."
"Hyper-V provided freedom to spin up development and test environments. As projects were created, an environment could be created and applied."
"Hyper-V can expand storage. For instance, if I have a VM running on NetApp or another platform, I can expand the storage without interrupting operations. It is useful when I need to quickly allocate more storage without causing downtime or performing maintenance tasks."
"I like that Hyper-V is like a virtual environment. I like to use VMware because of the resource requirements. In Sri Lanka, most of the customers use the Hyper-V GUI. When installing the interface with the Windows version, we also install the Hyper-V feature on the server. This is because they require more features and memory. There are so many features that they have embedded in Hyper-V that are useful."
"The virtual SAN feature is helpful."
"The initial setup of Hyper-V is far easier than VMware."
"I find that most of the competition is more or less the same. However, Hyper-V is, when you compare it to the older platforms like VMware, a little bit more advanced at this stage."
"It offers a high-availability environment."
"Very cost-effective."
"Our production servers are running in Linux, and this solution supports that environment well."
"It is an easily scalable solution."
"The GUI interface makes the management of KVM easier than ever before."
"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."
"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."
"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."
"The product's initial setup phase was simple."
"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."
"The solution is very stable. I don't recall any bugs or glitches. It's reliable. It doesn't crash or freeze."
"I rate Oracle VM's scalability a ten out of ten."
"It's easy to adjust the size up and down."
"It's not a very expensive product."
"Good visualization hypervisor."
"VMware is user-friendly, with clear integration and detailed migration."
"In my opinion, it would have been better to truncate the site-to-site replication."
"We have our cluster connected to a Dell EMC VNX (SAN). The Hyper-V nodes are on Cisco UCS blades, and everything is interconnected via fiber. I attempted to use a virtual Fibre Channel connection to present a SAN volume to a VM but was not able to make that work."
"There is a hard limitation of 20 gigs per file with Dropbox, so you've got to overcome that by chunking the zip files into something smaller and manageable."
"Hyper-V systems need a lot of admin effort because security updates and monthly updates require rebooting after the update."
"Storage via SMB3."
"The product can be a bit difficult to use."
"In my opinion, read the documentation carefully. If you do not, you will have problems."
"Hyper-V's management platform falls short in terms of scalability, especially when handling multiple Hyper-V servers. VMware has a central console to pull in all your VM servers, so you can easily manage them all through one console. You can manage servers in Hyper-V's admin centers, but it's not as scalable. It's doable with a couple of Hyper-V servers, but it becomes harder to manage when you get over two or three Hyper-V servers."
"Business continuity features need to be added."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"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 main drawback in the solution is probably disaster recovery."
"Monitoring and resolution could be improved."
"We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide. A lifecycle component would be very beneficial."
"KVM is very difficult to manage and run on daily operations."
"Integrating with the internal system is not very easy."
"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."
"An expanded data transfer option is one of the features I would like to have added."
"The usage could be easier, and more user-friendly."
"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."
"If you do a gap analysis between VMware and Oracle VM, you can't do VM Snapshot. That's one thing you can't do. It's a sort of a snapshot, but it's not really Snapshot technology. It requires that you're running on CFS-2."
"We do have a little trepidation with systemd, as it does have a learning curve."
"Oracle VM should have centralized storage, without which you can't clone or move one VM to another."
