KubeVirt VMs run within regular Kubernetes pods, where they have access to the standard pod networking and storage. With KVM virtual machine being a Linux process, why not use Kubernetes to orchestrate virtual machines? Kubernetes is orchestrating containers (processes) across a cluster of hosts, network and storage. Virtualization is mostly used in managed environments, orchestrating virtual machines (compute) across a cluster of hosts, network and storage. The beauty and simplicity of KVM virtualization is that virtual machines are Linux processes, benefiting from existing Linux features. It was built as a way to make it easier to move from a virtual infrastructure to a Kubernetes and container based infrastructure, one workload at a time It was created by Red Hat to enable Kubernetes to provision, manage, and control VMs alongside container resources. It uses the same native constructs of Kubernetes such as scheduling, storage, networking, monitoring and tooling via kubectl. It is a set of controllers (CRDs) which allow a way to run Virtual Machine on Kubernetes.
#WHAT IS KUBERNETES LICENSED UNDER LICENSE#
KubeVirt, started in 2016 and is an open source project distributed under an Apache 2.0 License from 2017. In the same way that we now accept hybrid cloud infrastructure as the norm, so to, will it come to pass that Kubernetes driving containerization will live side by side with traditional server infrastructure such as virtualization…īut what if you could have both together… containers and virtual machine controlled by the same management plane… this is were KubeVirt comes into play. The reality is that physical and virtual machines will not be going away even with this shift to cloud and containers. It has strong roots with with developer lead application development driving adoption past the mainstream to be the dominate force as a modern application platform. I’ll admit that when I first saw the KubeVirt appear on my radar I thought that someone was pulling my leg… Kubernetes rise in the IT professionals day to day vernacular has resulted in a ton of interest to understand what it is and what it does.
