Chief Technology Officer at Rohill
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 has a rich options set which can be directly used or via wrappers, such as libvirt."
"The most helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so."
"What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"Compared to other virtualization solutions KVM is much faster and better at managing resources."
"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."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"The initial setup was very easy."
"When you run templates on the containers on Virtuozzo they have a lot of back-ups."
 

Cons

"Some things are pretty basic, and they could be more robust with more detail."
"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."
"Management of underlying volumes."
"The solution’s user interface could be improved and made more user-friendly."
"The solution overall is just okay."
"We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide, and a lifecycle component would be very beneficial."
"Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view."
"KVM is very difficult to manage and run on daily operations."
"Odin Virtuozzo has poor support and needs to improve."
 

Pricing and Cost Advice

"I use KVM for free through Proxmox, which offers a free license alternative."
"KVM is free."
"The solution is extremely cheap in China."
"We had some problems with the licensing."
"KVM is an open-source solution."
"KVM is priced reasonably."
"It is free for everyone."
"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."
