good choice to deploy OBS in kubernetes.

running an instance is easy. Getting it integrated, solving the KVM nesting
overhead (about 50% slowdown, but you may ignore it, if acceptable) and
integrating into the dispatch queue is a complete different topic.

KVM nesting overhead? what KVM nesting? Kubernetes is docker containers, not
virtual machines...

Based on my understanding, there could be two possibilities.
1. When the kubernetes cluster especially the work nodes are deployed
on KVM based instances, especially on public cloud.
2. When the container runtime is based on VM solution, for instance
Kata container gvisor or firecracker. sometimes it's a requirement due
to the security reason.
3. Or both.
