Low latency in mission-critical environments with different virtualization environments
The most valuable feature of KVM is its superior real-time performance, which results in lower latency compared to alternatives like VMware and Microsoft. The ability to switch from one VM to another efficiently, thanks to the implementation of a real-time kernel, ensures delays remain minimal, thereby meeting our organization's performance requirements. This improved latency is critical because any delay in voice transmission could lead to life-threatening situations. Additionally, KVM being open-source means that we are not obligated to pay for licenses, which significantly reduces costs and simplifies license handling for ourselves and on behalf of customers.

Significant backup for containers, but the customer service is terrible
Anyone considering this solution should not compare it to the old versions. They should be a partner with Virtuozzo and run all the certifications. Also, they need a good lab to understand the technology and how they can apply that technology conveniently. This is very commercial software. It does not have support, so you will need to be hands-on. I would rate Odin Virtuozzo a six out of 10 overall.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Over the years, many customers were happy that they were able to choose between VMware, Xen and another alternative - KVM."
"One of the best features of KVM is its user-friendly interface."
"The solution is very light when you are putting your Operating System on it, and you forget that there's a virtual layer on your solution because you are using it as if it was a whole computer."
"What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines."
"The GUI interface makes the management of KVM easier than ever before."
"Scaling the solution is easy. You just have to add more hardware."
"The scalability part should be better."
"KVM is very complete, it is very powerful, but people are used to graphical QEMU and that is an issue."
"When you run templates on the containers on Virtuozzo they have a lot of back-ups."
 

Cons

"The solution overall is just okay."
"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."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"We have experienced some strange problems with instability using KVM."
"KVM is very difficult to manage and run on daily operations."
"The speed is around thirty percent slower than another competitor. This would be something to work on."
"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 am sorry to say that online propaganda made believe that KVM is a mature product that should be considered for production. I think KVM may be good for a lab where the VMs aren't critical."
"Odin Virtuozzo has poor support and needs to improve."
 

Pricing and Cost Advice

"KVM is free."
"​It is free and can be run from your laptop, if needed, unlike VMware.​"
"This solution came with the Linux license."
"There is no cost involved in the use of KVM, as it is open source."
"I use the free version of KVM, and I'm not sure if there is a paid version."
"It is cheaper than other competitors like VMware or Hyper-V."
"The solution is extremely cheap in China."
"I use KVM for free through Proxmox, which offers a free license alternative."
"The license for Odin Virtuozzo is based on consumption on demand."
