We performed a comparison between Citrix Hypervisor, KVM, and Oracle VM VirtualBox based on real PeerSpot user reviews.
Find out what your peers are saying about Proxmox, VMware, Microsoft and others in Server Virtualization Software."The solution's security is its most valuable aspect."
"The solution integrates well with other solutions, which makes it really strong as a primary solution to deploy."
"Citrix is easy to use and is stable."
"The support for this solution is phenomenal."
"The initial setup is easy."
"The solution is extremely user friendly."
"This solution allows the end users to clone, start, stop, or remotely control their VMs."
"The solution is easy to deploy. It's very easy to understand problems and read logs."
"The initial setup was simple."
"The initial setup was very easy."
"If you prefer command-line, there are all kinds of command-line options."
"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."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"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 appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"The snapshot feature is very powerful; it protects us from disaster."
"The scalability of the solution is very good."
"The initial setup was straightforward."
"It's a pretty good product in terms of monitoring."
"The most valuable aspects of the solution were the support and performance of the product and the flexibility it gives you to work."
"I like that it has a snapshot feature."
"The good thing is that it is multi-platform. Once you create a virtual machine in one particular environment, you can switch over to see if you can run it in other environments. For example, if you are on Windows and you create this virtual machine, you can actually go ahead and change the operating system. You can switch it over to Linux or Mac OS and see if you can run the VirtualBox on those particular machines. It even runs on some of the commercial operating systems that are not mainstream, such as Solaris and BSD. These kinds of operating systems are also supported by VirtualBox. The other thing that is good about VirtualBox is that it is open source. So, if you need to do any modifications for your own purposes, you can just download the source, modify it, and deploy it in your environment. It is pretty good and very versatile. You can create and manipulate virtual machines from the command line, which is also very important. It's something that some other products on the desktop side do not have. VMware Fusion and Parallels Desktop don't have a good command-line interface to create and manipulate virtual machines, whereas VirtualBox has it out of the box, which is pretty good."
"The cloning is a very useful tool."
"The manageability of the solution needs improvement. It's an extremely bad product to handle."
"I think the technical support could be better."
"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."
"The self-service user portal needs to be more granular and be more customizable."
"The solution should be more flexible and allow for greater customization."
"We'd like them to add more automation to the product."
"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."
"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."
"Technical support is not top-notch."
"The product must provide better performance monitoring features."
"Some things are pretty basic, and they could be more robust with more detail."
"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"I have encountered difficulties in getting the tool's documentation."
"We still occasionally build Interlaced Wireless Protection within our environment. The ecosystem entails areas, where we support agents, and release backup and security solutions. Collaboration with independent software vendors (ITOLs or ITOLED) is necessary to offer these solutions to customers. However, the scope of the ecosystem in KVM is not as extensive as that of VMware's. In contrast, VMware boasts a robust partner network, allowing for comprehensive customer solutions. On the other hand, KVM’s ecosystem is comparatively limited in comparison. I would like to see FT features in KVM."
"Monitoring and resolution could be improved."
"Basically, the GUI and command-line interface need improvement."
"The communications setup lags. It does not connect properly so the batching and networking is a bit slow."
"The memory and hardware usage could be a little bit lighter. Right now, it's quite heavy on the usage. The CPU usage should be lower."
"Oracle needs to improve its hot virtual machine migration. It didn't work as intended. It should allow us to migrate between virtual machines, without stopping the database."
"The user interface needs to be improved."
"There are a few bugs that need to be updated."
"The user interface needs to be improved."
"It would be good if we could use Hyper-V Windows subsystems with Linux and VirtualBox on the same instance. Currently, to be able to use VirtualBox, we have to restart the machine into an instance of Windows where Hyper-V is disabled, which is understandably very inconvenient."
