Does KubeVirt v1.8 replace my hypervisor?

No. KubeVirt runs *on* hypervisors (currently KVM by default). The new Hypervisor Abstraction Layer lets you swap which hypervisor KubeVirt uses, but you still need one. Think of it as the orchestration layer that goes on top of your existing infrastructure.

Can I use KubeVirt v1.8 on my current Kubernetes cluster?

Yes, if you're running Kubernetes v1.35 or compatible versions. KubeVirt maintains compatibility with recent Kubernetes releases. Check the release notes for your specific version's support matrix.

How much network bandwidth does the new backup feature actually save?

It depends on your workload change rate. The more static your VMs, the more you save. Teams doing incremental backups report 30-50% reduction in backup traffic compared to full copies, but real numbers depend on your actual data change patterns.
