Kernel-based Virtual Machine: "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
Kernel-based Virtual Machine is very well suited when one needs a single-node virtualization host or needs to build a complex demo setting on their own notebook (e.g. when demonstrating solutions to a customer).

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
I recommend using KVM if you want to start a proof of concept of OpenStack services because it is very simple to configure and has much documentation about it. If your IT environment is Linux based, KVM is a great alternative to virtualize your infrastructure. It works with Windows virtual machines, but it is better with Linux obviously.
