KVM Reviews

The most valuable feature of the solution is that KVM is much more flexible than Oracle VM. Multithreading in KVM is also a very good feature. Oracle VM supports only serial ports, so executions happen one after the other, while KVM supports parallel ports, allowing you to do multiple tasks at the same time, which also makes it a more flexible choice.

Sometimes, my company has some issues with the storage part, which is mostly not the fault of KVM but a problem with the storage. In general, I don't have any downsides or negative points related to the tool.

In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware.

I have been using KVM for five years. My company recommends KVM to potential customers.

Stability-wise, I rate the solution an eight out of ten.

It is an easily scalable solution.

My company communicates with Oracle Linux's technical support, and sometimes the support is good, while sometimes it may be a bit less.

My company has experience with Oracle Linux VM and Oracle VM apart from KVM. KVM and Oracle Linux VM are more stable and flexible compared to other products in the market. My company does not recommend products from KVM's competitors since we have an Oracle-centric environment, and most of the time, we get VMs with Oracle licenses only. Oracle VM will not do anything to improve the product since it can be described as an end-of-life product.

I rate the overall product an eight out of ten.

The most valuable feature of KVM is the hypervisor environment and how we can configure it with ease. Additionally, the interface is intuitive.

I have been using KVM for approximately two years.

KVM is a stable solution.

I have found KVM to be scalable.

The technical support has been good, we are able to receive help for complex environments.

I have previously used VMware and KVM is easier to use. However, they both have their strengths depending on their use cases. They are mostly equal. One of VMware's advantages is it has better support.

The initial setup of KVM is simple.

KVM is priced reasonably.

I rate KVM an eight 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.

I am using this solution in my home lab because I don't know this solution well enough to put it into production. I have many clients, and by putting KVM into production it would require several changes, which would require more experience.

In the meantime, I will continue to use VMware and ESXi.

I use both on-premises and cloud-based deployment models. I typically use this solution on the cloud because I have many dedicated servers. However, I also use it on low-powered hardware machines, like old laptops, to create a firewall, access the router, or use as an access point.

I like that this is an open-source solution. It is very powerful, and it's easy.

When you install Hypervisor with KVM, you can transform it into a server with the graphical QEME in minutes, then look at what you have and remove all graphical things and then you can restore what you had originally.

The virtual manager and the graphical QEMU for KVM need some improvement.

In the next release, I would like to see some changes made to the dashboard as it would be nice to see some icons and some graphics when you are showing this solution to clients.

MOP made some changes to the dashboard, but it made it more difficult and it's a bit complicated. Maybe this was done intentionally because this is an open-source solution with technical support as an additional fee.

This solution is very stable.

It's straightforward and recoverable, it's easy to do anything.

This solution is scalable. Ubuntu is the best version to scale because with the MAS you can set load balancing, and they offer a free account to manage the load balancing for up to ten servers.

Currently, I am the only user.

I haven't contacted technical support.

I have been using VMware, ESXi, and Linux and will continue to use them while I get more experience with KVM.

The initial setup is straightforward.

There is a lot of information available online. You can do it all by yourself, you just need the time and the will to do it.

This solution is an open-source, free platform with paid support.

You can virtualize anything now, but in my experience, they are good for Linux and Unix systems. I have also used Windows.

Even if you are using another platform hypervisor, as I do with VMware, you may get yourself in a situation where you want to install the KVM or at least the key tools. You can access RAM drives, or broken virtual hard drives, or migrate them to another type of hard drive.

KVM is very complete, it is very powerful, but people are used to graphical QEMU and that is an issue.

The solution performs well and has many tools. It offers everything that all other paid versions have. Everything is in your hands, all you need is the internet to access all of the information on KVM.

I would rate this solution a nine out of ten.

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.

I've used it a little bit for virtualization. I've been messing with it for the past month and a half, in an actual environment that goes to the outside world, anyway.

I have a cloud server running. I also have a web server. I'm using it mostly for hosting websites and basically having a cloud service, such as OneDrive or Google Drive.

The product overall has been useful, however, the solution is still too new to really give a concrete example as to how it's changed how the organization functions.

The solution is really easy to use. Basically, it takes just a few command-line statements to install and have it set up and running. From there, you can use the virtual manager, which is command-line. However, there's also a graphical user interface for it. It's just really easy to use. all-around

If you prefer command-line, there are all kinds of command-line options. You can pretty much run and manage all of the virtual machines straight from the command line, or you can use the practical user interface and do the same thing.  

I noticed that there are even other services like Multitask. You can use Multitask on KVM.

From my skill set and what I'm capable of, I wouldn't know how to say what could be improved as it works exceptionally well. I know that things can always be improved. 

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. That's one thing that's a little bit confusing. That's more systems administration, in general. If they would make it a little easier to do, then you wouldn't have to have so much systems admin knowledge in order to use one feature.

I tried to follow the information provided, however, then the partitions were added, the logical drive, and it didn't actually end up being initialized correctly. I'm pretty sure it's due to my own error, and not using it correctly. However, if they would have been clear on how to do it, or if they could even build a command that literally executes the necessary commands for you, just by typing, or using the virtual manager, that would have been helpful.

I've only used the solution for a short period of time, so maybe it's there, however, I'd like it if maybe they could combine some network manager type item in there to be able to bridge connections a little easier. Then, you wouldn't have to do it as a separate task. Perhaps their existing network management already includes that. I'm not sure.

I haven't used the solution for very long at all. I started using it about a month and a half or so ago, since I've had this server. It's all very new to me right now.

The solution seems to be quite stable. I haven't had any crashing, or any bugs or glitches so far.

I'm not sure if the solution can scale well or how easy it can scale as right now I'm having trouble figuring out how to do it correctly. It seems like it is a bit of a confusing process.

Basically, I'm a freelance contractor. Therefore, it's just me using the solution at this time.

I haven't used technical support yet. I haven't been on the solution for very long.

I didn't previously use a different solution. I just recently got this server.

The initial setup is pretty straightforward. It's not too complex. There are just a few commands from the command line, and then you're good to go. It's very easy and very quick.

I'm just a customer and an end-user. I don't have a business relationship with KVM at this time.

I'm using what should be the latest version of the solution right now.

I would advise other organizations that this solution is definitely a good choice. It's definitely something that's easy to use, however, you can have it on a fully functioning operating system that you're familiar with. Or, if you have a little less experience, it's something that you can get up and going really quickly. That said, it is still a type 2. That is a great thing. It functions, and it's under two pounds. It's basically like being on bare metal, which is really nice. 

Overall, I'd rate the solution at a nine out of ten.

I'm a senior Linux system administrator and we are customers of KVM. 

I like that this solution is open source, it was easy for me to configure and I haven't had any problems with it.

I think the UI could be developed more in the future because there are some issues with the graphics and some software that is very complex. A GUI for controlling the VMs would be a good additional feature. It's easy for us but it's difficult for others working with CLI.

I've been using this solution for over three years. 

KVM is stable, but the product from VMware E6 is not stable and I sometimes have issues with it and then the usage of RAM and CPU is costly in my experience. 

This solution is scalable. 

We did not initially have support but when I have used it recently it's been good. 

The initial setup is quite easy for me, I use CentOS. 

KVM is good and I recommend it. In the future, containers will be substituted by virtual machines and KVM need to adapt to be able to support that. 

I rate this product an eight out of 10.
