Linux KVM is a mature production ready solution
Virtualization was a turning point in technology because of its flexibility and reliability. Before virtualization, we had to deal with all the issues related to bare metal servers. Linux Kernel-based Virtual Machine became the industry de-facto for virtualization, especially for *nix related guess operating systems. It is very stable and reliable for production systems. We use virtualized servers for more than a decade on Kernel-based Virtual Machine technology with amazing results.
- Segregation of guess systems.
- Fair allocation of resources.
- Hardware virtualization.
- Handling of hardware failures.
- Hot migration of systems between KVM hosts.

- Fast provisioning of new servers.
- Huge drop of the cost of servers compared to bare metal.
- Easy upgrades of resources, sometimes now even requiring a server restart.
Kernel-based Virtual Machine is an open-source and free solution, compared to Virtualbox which is a product from Oracle.

The great tool contemporary virtual world.
Linux KVM is a powerful and free (in the case of using Ubuntu for example) virtualization tool. In our organization KVM plays a significant role in DevNet related implementations (especially by using in pair of network appliances + KVM with a variety of firewall/router/VPN box images). AT&T which is one of our carriers and the most well-known SP is also using KVM in its FlexWare environment (Juniper NFX hardware + KVM + vEX/vSRX images).
- Lightweight built-in implementation for all *nix based OS.
- Easy to deploy and manage VMs.
- Freeware (is you are using a free OS).
- Monitoring features (unclear SNMP MIB DB, do not support by the monitoring systems, like Solarwinds and etc.)

- Money saving.
The key points why I made my decision for KVM in comparison with VMWare are: Freeware software (I am using an Ubuntu server OS), Fewer resources usage, vSwitch using that provides the ability to configure dot1q trunks to/between VMs, Stability, and simplicity of using/troubleshooting, Well-known interface (for Linux geeks).

KVM - Open-Source virtualisation solution
We use virtualisation to segregate workloads and to reduce blast radius of certain classes of problems. Kernel-based Virtual Machine (KVM) is an open-source, flexible, and performant solution to our needs. It runs natively via virt-manager on SUSE-based products, which we use prefer for production usage.
- high-performance virtualisation
- no major problems with kvm

- KVM just works and gets out of the way
- KVM is working great with other open-source technologies like QEMU and libvirt
Compared to VirtualBox, KVM has simpler licensing terms and is supported by the operating system vendor. KVM also has more mature integrations with other open-source projects. Automating provisioning is simple with KVM since it is available in the package repositories of Linux distributions.

Great Linux-integrated virtualization foundation
I am a consultant who provides KVM-based solutions to customers from all sizes and industries.
At the customers, KVM is usually used by the IT departments, providing virtulization services to all kinds of users, departments and maybe even their customers.
Regarding the business problems KVM adresses:
KVM manages to provide a Linux-integrated virtualization foundation which enables IT departments to provide virtualized systems very fast and efficient. With enough knowledge, IT departments simply install Linux servers and start KVM VMs. The time frame from starting until VMs are up and running is very short, so IT departments don't necessarely have to buy virtualization products if they use KVM.

- KVM is really good at providing fast and reliable virtualization for Linux guests
- Since KVM is a kernel module, every VM is a Linux process which can be managed by Linux system tools
- KVM integrates very well with the management framework libvirt, which is why KVM can be integrated in automation tools as well
- KVM itself doesn't ship with a management interface
- KVM itself is a bit complicated to handle
- KVM needs Qemu to virtualize Windows guests

- KVM normally enables customers to fullfill their business goals very fast and it is free, so there is a very small time window from implementation to "investment is returned"
- If IT staff doesn't have hardcore Linux experience, they will need proper learning time until they'll be able to handle KVM
KVM is free and provides environments where guests can run their own Kernel while still performing very well.
It is also very native to work with KVM since it is integrated within the Linux Kernel.
In comparison to VirtualBox or VMware Player, KVM is far more performant.
In comparison to commercial virtualiuzation solutions, KVM does very well because it is free.

We are using Kernel-based Virtual Machine (KVM) as part of our storage solution (OpenStack based). Our solution provides low-cost disk volumes to researchers to use for archiving and data backup. The volumes are provided by KVM virtual machines orchestrated by OpenStack Cinder. It was easier to implement this solution with KVM than XenServer Hypervisor.
- Easy way to work with OpenStack
- Better performance with the Linux OS
- Lowest Cost
- Complex networking
- GPU processing is not fully supported
- It's hard to set up without support tools

- Capital expenditure costs are low, because is open-source and free
- Operational expenditure costs are medium because it's necessary [to have] an IT team with experience in Linux
- First step to the virtualization world. Wake up, we are in the 21st century
- XenServer and VMware ESXi
It is a very reliable solution that can be used for x86 architecture virtualization with low overhead. It is a free and open source software. Easy to use withOpenStack.
