Open Source KubeVirt: VM Management With Kubernetes Is a Work in Progress
- KubeVirt is an open source project that allows virtual machines to run alongside containers within Kubernetes, backed by Red Hat, NVIDIA, and other tech companies.
- While KubeVirt enables VMs and containers to coexist, it currently has limitations for scaling VMs on Kubernetes and requires significant changes to existing IT infrastructures.
- Functionality of KubeVirt includes basic hypervisor admin features but lacks advanced operational capabilities found in established VM management offerings.
- KubeVirt's use cases include infrastructure provisioning and hosting VMs for Kubernetes clusters, but lacks integration with storage systems.
- KubeVirt is designed for Kubernetes environments, requiring organizations to fully containerize workloads, and faces challenges in managing large-scale VM deployments.
- KubeVirt's maturity level is still in incubation within CNCF, indicating ongoing development needed to reach graduation status for enterprise adoption.
- Gartner advises organizations with existing VM infrastructure to use platforms with proven VM management capabilities rather than adopting KubeVirt due to technical and operational limitations.
- Despite progress, KubeVirt's adolescent stage and technical complexities make it a risky choice for most enterprise environments, according to Gartner analyst Michael Warrilow.
- As KubeVirt evolves, it may offer potential benefits for managing small numbers of VMs, but significant risks and challenges remain for broader enterprise adoption.
- Gartner estimates that KubeVirt adoption for on-premises production virtual workloads will remain below 10% through 2028, with caution advised on its use in critical operations.
- Adopting KubeVirt without justifiable reasons may introduce avoidable technical risks and not necessarily improve performance, reliability, or security for enterprises.
