KVM Reviews

Running virtualization clusters with more than 300 VMs.

The platform changes from hardware to virtualized whenever possible.

• Open source
• The ability to execute live migrations
• Linux, a base OS.

Management of underlying volumes.

We primarily use it to write the payroll solution fort Windows Server 2012 and 2018.

The solution is very light when you are putting your Operating System on it. You forget that there's a virtual layer on your solution. You are using it as if it was a whole computer. It's like having an entire computer that you've launched and have running with the Operating System that you need to work with.

The solution should be more user friendly despite that some interesting graphical solutions are available to manage the VMs. it would be usefull that the solution integrate the VM snapshot features and make it graphical, so we have a VM infrastructure more complete and easy the backup/restore in case of issue.

The solution is very stable. It's been stable since I started using it in 2014.

Scaling the solution is easy. You just have to add more hardware.

I've never needed to contact technical support. To me, that's a sign of a good solution.

The initial setup is easy. There is a lot of documentation online, so if there is a problem the online information will help you. 

Deployment only took one hour.

I handled the implementation myself.

We're using the on-premises deployment model. We're using the community version of the solution.

I'd rate the solution nine out of ten.

We primarily use KVM to deploy application servers and host websites. We aim to explore its features further to enhance our projects and implement diverse environments within this virtualization software.

I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting.

I have encountered difficulties in getting the tool's documentation. 

I have been using the product for two years. 

In my experience, I haven't encountered any issues with stability. Since I installed and started using it, the system has been working very well.

My company has five users for the product. 

I haven't contacted technical support yet. 

KVM's initial installation was a bit challenging for me, but I believe it's more manageable for those with Linux expertise, especially given the available documentation. It took me approximately five days, working about three hours per day, to fully implement it. 

I did the deployment myself. 

I rate the overall product a seven out of ten. You need to have good knowledge of Linux and networks. I would recommend the product to my colleagues.

We are a consulting company and I work with a lot of solutions to compare them and find out which ones are good for my customers.

The primary use case for this solution is virtualization.

I use this solution in on-premises data centers.

Compared to other virtualization solutions KVM is much faster and better at managing resources. For example, we compared XEN, KVM, and Vmware for creating development infrastructure for our programmers, we ended up using KVM.

The GUI interface makes the management of KVM easier than ever before.

The performance of this solution is great.

This solution is lacking in features such as management and integration.

• This solution needs better integration with desktop virtualization.
• Better integration with storage solutions is needed.
• Business continuity features need to be added.
• The live migration needs to be improved.
• You cannot run this application in a data center using only the GUI, so you have to have some knowledge with Linux in order to best manage it.
• Better network management software is needed.
• Features like vSAN are not available on KVM.
• Integration with Kubernetes would be an improvement.

Generally, this solution should be made easier to use. Many customers don't have enough experience with Linux or a deep understanding of operating systems, and they just want to use the product. This together with a lack of features has led customers to choose VMware.

I have been working with this solution for more than ten years.

This solution is limited in terms of scalability. I think that it is suitable for a mid-range company, but for a larger company, it is not quick. It does not have features for companies that need expandable solutions.

This solution is not used directly by the end-users. If KVM is installed in their data center then they just use the virtual machine. Users don't care about infrastructure, they're just looking for stability and use the operating system for their service. It is the administrators who use this product. Typically, there are two or three administrators in each data center. In terms of end-users, I have seen more than one hundred concurrent users.

We do not have access to Red Hat support from our country.

For technical support we depend on the internet and the knowledge of our administrators.

I have used XenServer and VMware, and the performance of KVM is better than these.

When it comes to management, integration, business continuity, and live migration, KVM is lacking features and VMware is better in this area.

The initial setup of this solution is not hard, but when you want to use this product in your data center, you have to use the command-line interface to better manage it. You cannot run this application using the GUI alone, so if you don't have enough knowledge with Linux then you may have some trouble.

Most of our solutions are implemented in-house as well as this one.

This solution can be used for free but if you have an expert team on Linux OS, select this one. if you don't have them, forget about it.

I evaluate options such as XenServer, VMware, and KVM every six months in order to choose the best product for my customers.

I have been using this solution since before it was owned by Red Hat, when it was community-based. It is easier to manage than ever before because you used to have to use the command-line interface, instead of the GUI.

I do not recommend this product for those looking for a stable and scalable virtualization solution because they will ultimately have problems in their data center. Just two weeks ago, I helped a friend of mine to migrate from KVM to VMware.

I think that if Red Hat worked on some business continuity features and add them to KVM then it would receive a better grade and be a more competitive solution.

I would rate this solution a five out of ten.

We integrate KVM as part of our product. I'm the CTO of our company. 

The solution is very cost-effective. VMware is exorbitantly priced and compared with other products KVM is much cheaper especially in the public cloud scenario.

Their support for snapshot and revert could be improved. I'd also like to see the product achieve high availability across clusters and to have more support for Apache CloudStack.

I've been using this solution for over a year. 

We haven't had any issues with stability. 

Scalability is fine, no problems at all. 

We have worked with certain support vendors and they're fine. In particular, we work with one of the Red Hat partners and we're quite happy.

The complexity or otherwise of the initial setup depends on the situation but generally it's not too difficult. We offer our customers maintenance support which generally involves update patching.

KVM offers both an open source and licensed version. 

Before deployment, it's worth checking whether the solution fits your use case and how it would be used across various large deployments. Test it before implementing. 

I rate the solution seven out of 10. 

It is useful for everything for which you would use VirtualBox. It is the kernel virtualization model in Linux. I am using the 5.10 kernel. It comes with the Linux operating system.

It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox.

Its resource usage can be improved. 

I have been using this solution for several years.

It is stable.

There is no support for it except in the community. If you want support, you have to pay a company that provides support for this platform.

There is no installation as such.

It is free for everyone.

I would recommend this solution to others. If they were using Linux, this is a requirement.

I would rate KVM an eight out of ten. If KVM uses less resources, it might improve my score.

It gives us live VM migrations.

It allows us to virtualize our entire IT Infrastructure without any software cost. We only need to spend money on support and deployment.

Used since 2009 from version 0.8, so 6 years now.

No.

No.

It's scaled for us since version 0.8.
