Container-native virtualization lets developers bring virtual machines (VMs) into containerized workflows by running a virtual machine within a container. By combining these two technologies into a single management platform, organizations take advantage of the simplicity and speed of containers and Kubernetes while still benefiting from the applications and services that have been architected for virtual machines.
Container-native virtualization acknowledges that many organizations are using both container and virtual machine technologies today and delivers an efficient process to manage both in one centralized platform.
KubeVirt is the open source project that makes it possible to run virtual machines in a Kubernetes managed container platform. KubeVirt delivers container-native virtualization by leveraging KVM, the Linux Kernel hypervisor, within a Kubernetes container. KubeVirt provides services like those associated with traditional virtualization platforms, providing the best of both mature virtualization management technology and Kubernetes container orchestration. Started by Red Hat, KubeVirt is now a CNCF Sandbox project.
Making virtualization Kubernetes-native
Container-native virtualization is a technology preview feature within Red Hat OpenShift. When container-native virtualization is enabled for a Red Hat OpenShift cluster, developers can create and add virtualized applications to their projects from the service catalog in the same way they would for a containerized application. The resulting virtual machines will run in parallel on the same Red Hat OpenShift nodes as traditional application containers.
Container-native virtualization adds new objects to your OpenShift Container Platform cluster via Kubernetes custom resources to enable virtualization tasks. These tasks include:
Container-native virtualization enables businesses to deliver a platform that is capable of:
Container-native virtualization is ideal for teams that are shifting to cloud-native application development and have a large investment in conventional virtual machine technology.
