What does KubeVirt 1.8's hypervisor abstraction layer actually do?

It decouples KubeVirt from KVM dependency, allowing you to swap hypervisors (Firecracker, cloud-hypervisor, etc.) without rewriting your control plane. KVM remains the default, but alternatives are now officially supported.

Is KubeVirt ready to replace VMware for my production workloads?

Depends on your workload. Standard VMs on Kubernetes-native infrastructure? Yes. Complex legacy environments with custom networking and decades of VMware integration? That's still a migration project, but 1.8 closes most technical gaps.

How much can you actually save by migrating from VMware to KubeVirt?

Portworx reports customers seeing cost reductions up to 50%, primarily through consolidation of infrastructure and elimination of VMware licensing audits. Your mileage varies based on current VMware contract terms.
