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 stable."
"One of the best features of KVM is its user-friendly interface."
"KVM is a very good solution for the user ecosystem."
"The initial setup was simple."
"The most valuable feature of KVM is the hypervisor environment and how we can configure it with ease."
"Compared to other virtualization solutions KVM is much faster and better at managing resources."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"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 virtual manager and the graphical QEMU for KVM need some improvement."
"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."
"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."
"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."
"The virtual manager and the graphical QEMU for KVM need some improvement."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"Business continuity features need to be added."
"Their support for snapshot and revert could be improved."
"Odin Virtuozzo has poor support and needs to improve."
"Odin Virtuozzo has poor support and needs to improve."
 

Pricing and Cost Advice

"KVM is an open-source product that works well for us."
"KVM is an open-source solution."
"KVM is free."
"It is cheaper than other solutions out there on the market."
"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."
"We had some problems with the licensing."
"I use KVM for free through Proxmox, which offers a free license alternative."
"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."

Far from being an expert, my opinion is that the positive sides of KVM are: Lower costs and open-source which gives the abilities to customize it according to the specific needs of each customer.
