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

"The product is really good...One can get good performance because of kernel-based virtualization."
"The most valuable feature of KVM is its stability."
"I think nine out of the ten supercomputers in the world use Linux KVM, so I think that attests to the fact that it is a scalable product."
"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."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"The key aspect is that the KVM directly interacts with the Kronos. There's no clear indication of indirect communication with Kronos. It is not linked to Kronos, and interaction is straightforward without any intermediaries."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"It allows us to virtualize our entire IT Infrastructure without any software cost."
"When you run templates on the containers on Virtuozzo they have a lot of back-ups."
 

Cons

"Business continuity features need to be added."
"KVM is very difficult to manage and run on daily operations."
"Monitoring and resolution are features which could be improved and I've found that if the product has not been used for some time, it needs to be re-set."
"I have encountered difficulties in getting the tool's documentation."
"Management of underlying volumes."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"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."
"The virtual manager and the graphical QEMU for KVM need some improvement."
"Odin Virtuozzo has poor support and needs to improve."
 

Pricing and Cost Advice

"The solution is extremely cheap in China."
"​It is free and can be run from your laptop, if needed, unlike VMware.​"
"This solution came with the Linux license."
"The tool is free."
"We had some problems with the licensing."
"It is free for everyone."
"KVM is priced reasonably."
"This solution is an open-source, free platform with paid support."
"The license for Odin Virtuozzo is based on consumption on demand."
