Kubevirt
KubeVirt is a Kubernetes virtualization platform and cloud-native hypervisor manager. It provides a runtime environment that allows virtual machines to be defined, launched, and managed as declarative resources within a Kubernetes cluster, enabling them to run alongside containers on the same nodes.
The system enables the hybridization of cloud infrastructure by combining traditional virtual machines with containerized workloads on a single shared platform. It supports the live migration of running virtual machines between physical hosts to facilitate cluster maintenance and load balancing.
The platform covers broad virtualization management capabilities, including the orchestration of machine lifecycles, power control, and direct console access for debugging. It also includes dedicated network configuration for secure machine migration between hosts.
