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

"There is a lot of value with an open source solution because you have some freedom of changing how the system behaves and looks because it's open source."
"On the other hand Vmware workstation is a Type 2 hypervisor meaning that this software is going to interact with the host without really modifying it."
"KVM, as a native virtualization solution, is a complete and fully adequate system for small businesses that need to reduce costs, and also to make maintenance easier."
"What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines."
"Our production servers are running in Linux, and this solution supports that environment well."
"It is an easily scalable solution."
"It allows us to virtualize our entire IT Infrastructure without any software cost."
"The scalability part should be better."
"When you run templates on the containers on Virtuozzo they have a lot of back-ups."
 

Cons

"We are not getting good support from KVM, and it is not that user-friendly."
"Monitoring and resolution could be improved."
"Its resource usage can be improved."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"The solution’s user interface could be improved and made more user-friendly."
"The KVM technical support is really bad. It has a number of empty channels for support."
"Technical support is not top-notch."
"KVM is very difficult to manage and run on daily operations."
"Odin Virtuozzo has poor support and needs to improve."
 

Pricing and Cost Advice

"The price is fair compared to others. But in our local market, it's a problem to get budget approval from management. That's why they are trying to get those products so we can give them the price benefit. But if you consider the international market or other products, it's sometimes better than their price."
"The solution is extremely cheap in China."
"​It is free and can be run from your laptop, if needed, unlike VMware.​"
"The product's pricing is above average but cheaper than that of VMware. I can't provide specific licensing costs, but we have a contract with Red Hat for client support that covers everything. There are no additional costs beyond the standard licensing fees."
"One only needs a subscription to Oracle Linux. So, it's cheaper with Oracle Linux's subscription. It is not very expensive. In short, the solution is open source, and you need only a subscription."
"I use KVM for free through Proxmox, which offers a free license alternative."
"It is free for everyone."
"We had some problems with the licensing."
"The license for Odin Virtuozzo is based on consumption on demand."
