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

"I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective."
"Low cost, if not lowest, with great performance and scalability, and security is top-notch while being free."
"The KVM service is well managed with a central policy interface."
"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."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"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 has benefited our organization by enabling us to assess different virtualization solutions with reduced latency, which is crucial for guaranteeing the reliability and real-time performance of our communication systems."
"The most valuable feature of KVM is its superior real-time performance, which results in lower latency compared to alternatives like VMware and Microsoft."
"When you run templates on the containers on Virtuozzo they have a lot of back-ups."
 

Cons

"The KVM technical support is really bad. It has a number of empty channels for support."
"The networking with wireless devices needs improvement."
"The solution should be more user friendly. We are struggling with the command lines."
"The main drawback in the solution is probably disaster recovery."
"The only negative aspect of needing hardware support is a fully functional KVM can be dropped. It would be nice if the support for other platforms, like ARM or Risk, were as good as the x86 one. However, with the democratization of Chromebooks based on these chips and mobile devices, it will not take long for that to happen."
"I think the management console has room for improvement. It could be more straightforward and user-friendly, like VMware's Console Management. This would make it easier for system admins to use and reduce training needs."
"One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy."
"They could provide a more comfortable and easier-to-manage interface for the product, whether text-based or graphical. It can be challenging to manage without the support of additional tools."
"Odin Virtuozzo has poor support and needs to improve."
 

Pricing and Cost Advice

"The solution is extremely cheap in China."
"There is no cost involved in the use of KVM, as it is open source."
"KVM is an open-source product that works well for us."
"It is cheaper than other competitors like VMware or Hyper-V."
"I have no information on the cost of KVM because I downloaded it for the lab and not for production. It's free, but I don't know if that's the case for people using it in a production environment."
"​It is free and can be run from your laptop, if needed, unlike VMware.​"
"It is cheaper than other solutions out there on the market."
"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."
"The license for Odin Virtuozzo is based on consumption on demand."
