We performed a comparison between Citrix Hypervisor, KVM, 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."Citrix Hypervisor does a great job overall, such as the virtualization of the host. It's very easy to manage the virtual machine, to create, and configure high availability."
"This is a dependable solution for virtualization with a good community for product support."
"The most valuable features are being able to host many virtual machines and being able to patch machines."
"The onboarding process is pretty straightforward."
"The initial setup is easy."
"What I find most valuable in Citrix Hypervisor is its licensing policy, because you'll get it for free if you buy a Citrix XenDesktop license. You don't need to spend additional money on the Citrix Hypervisor because you can manage both the Citrix XenDesktop and the Citrix Hypervisor with just one license, so you can save on cost. I also like that the solution is good support-wise. Hardware support is also faster compared to other solutions."
"The compatibility of the solution is its most valuable feature. It's compatible on almost every cloud these days."
"We can easily migrate VMs from one host to another."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"The GUI interface makes the management of KVM easier than ever before."
"I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"The product is really good...One can get good performance because of kernel-based virtualization."
"Good screen and keyboard sharing feature."
"I have found KVM to be scalable."
"The product offers good stability."
"Security-Features; vSphere does offer quite a bit of security stuff built-in. It is nice to know that we can have the virtual machines encrypted, so that if somebody were to get a hold of any of those files, we don't have to worry about them actually being used. Since we do have so many different departments and areas with a lot of people that need access into the solution, we can use the role-based access controls to really restrict and control who can do what, so everybody can do what they need to do, but they can't do anything else past that."
"The pricing of the product is reasonable."
"vMotion radically changes the way we think about how we can operate a large infrastructure, and notably, in terms of proactive maintenance."
"I use customization to prevent any network and DNS collisions to the router."
"The benefit of the solution is that you can create template-based servers within minutes. If you were to use a physical server, it would probably take several hours, if not a whole day, to get everything set up the way you need."
"Stability and scalability are the most valuable features of this solution."
"The most valuable features are its flexibility and the ability to move workload."
"I am not very sure about how flexible Citrix Hypervisor is with different types of infrastructures. I only know it is flexible with Nutanix, but I am not sure if it is also flexible with others. They can make its integration with other platforms or OEMs easy. They should also make it easy for users to manage their infrastructure. Citrix should make compatibility information related to a hypervisor easily available in a datasheet. Citrix isn't really recognized in this part of the world, and they need to expand their solution and make it more available. There are a lot of customers and companies that are looking for a solution like Citrix, and it should be available in this part of the world. They need to educate people more. Technically, it is good and flexible and has good ability, but it is not as much known as VMware or Microsoft. Their support should also be improved. Currently, if you don't have an updated version, they will not give you the attention."
"I find that the features in Citrix Hypervisor are not as rich as with VMware. It would be a benefit if they had some of the other features VMware has, such as the ability to expand a drive on the fly. You do not have to take down the machine to do it but in Citrix you do."
"The solution would benefit from faster technical support."
"I think the technical support could be better."
"Live migration is something that can be improved."
"Assigning the order of virtual server startup is not very easy and this can be improved."
"The interface has to be updated."
"The solution is too expensive and people are kind of moving away from Citrix. It's starting to become a problem. It is a primary reason that while we are rebuilding we're going to seek out open-source solutions."
"The networking with wireless devices needs improvement."
"KVM is very difficult to manage and run on daily operations."
"The KVM tech support is really bad. They are not very responsive."
"Business continuity features need to be added."
"The main drawback in the solution is probably disaster recovery."
"I have encountered difficulties in getting the tool's documentation."
"The product must provide better performance monitoring features."
"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."
"I would like to start to using NSX in the next release."
"It's an expensive solution."
"We previously had a hard time using tech support."
"Technical support is not that great. It is too slow."
"I feel that the scalability of the solution should be improved."
"Get the HTML5 client to 100% parity to replace the Flash client."
"The vSphere Client always feels slow, and/or like it doesn't keep up with what I'm trying to do. So I usually use the thick client most of the time."
"The one area where I would love to see an improvement is the HTML5 client. It's great, but it could get better."
