Lan Tuong - PeerSpot reviewer
Useful to manage the virtual environments
The most valuable features of KVM for us are the console, which allows us to build or clone VMs quickly, and the ability to take snapshots and recreate new VMs rapidly. That's one of the things we love about KVM. The built-in management console, Auto KVM, is the most valuable tool for managing our virtual environments. We use it most to create and fire up new VMs or clone them for customers based on requests. The migration tools have worked quite well for us. We're moving from an Oracle Solaris platform for KVM logical domains, upgrading, and using KVM from Red Hat. It's slightly different but very similar to Oracle Unbreakable Linux, which is basically a clone of Red Hat. Oracle's console is easier to use than Red Hat's, though.

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

"If you are a Linux desktop user, KVM is the solution to go with if you have to start virtual machines with Linux or other operating systems with almost zero extra configuration needed."
"The performance is great."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines."
"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."
"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."
"I find the density of the product most valuable. It is density that a technologist can just assign page merging. This is what makes KVM one of the important players of the virtualization market."
"One of the best features of KVM is its user-friendly interface."
"When you run templates on the containers on Virtuozzo they have a lot of back-ups."
 

Cons

"I believe KVM offers a unified answer, while ProxMark addresses orchestration. KVM lacks orchestration. If the aim is to centrally oversee multiple KVMs – let's say to freeze them – a centralized management solution is absent."
"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."
"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."
"KVM is very difficult to manage and run on daily operations."
"Technical support is not top-notch."
"The solution overall is just okay."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"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."
"Odin Virtuozzo has poor support and needs to improve."
 

Pricing and Cost Advice

"This solution is an open-source, free platform with paid support."
"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."
"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."
"The tool is free."
"It is cheaper than other solutions out there on the market."
"The solution is extremely cheap in China."
"The license for Odin Virtuozzo is based on consumption on demand."
