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

"KVM is very complete, it is very powerful, but people are used to graphical QEMU and that is an issue."
"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, and from there you can use either the command-line virtual manager or the graphical user interface to pretty much run and manage all of the virtual machines."
"Our production servers are running in Linux, and this solution supports that environment well."
"It offers a high-availability environment."
"The tool's most valuable feature is backup. The product makes it easy to manage virtual machines. Other tools require third-party applications like VMware and vSphere. However, KVM doesn't require these applications."
"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 KVM service is well managed with a central policy interface."
"The most valuable feature of KVM is the hypervisor environment and how we can configure it with ease."
"When you run templates on the containers on Virtuozzo they have a lot of back-ups."
 

Cons

"Setting KVM up and running it with dozens of parameters can be annoying."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"The stability of this solution is less than other products in the same category."
"Monitoring and resolution could be improved."
"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 networking with wireless devices needs improvement."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"Technical support is not top-notch."
"Odin Virtuozzo has poor support and needs to improve."
 

Pricing and Cost Advice

"It is cheaper than other solutions out there on the market."
"KVM is an open-source solution."
"There is no cost involved in the use of KVM, as it is open source."
"KVM is free."
"KVM is an open-source product that works well for us."
"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."
"The tool is free."
"It is cheaper than other competitors like VMware or Hyper-V."
"The license for Odin Virtuozzo is based on consumption on demand."
