well, the actual issue (IMHO) is that this meta-orchestrator (karmada) needs quorum even for a single node cluster.

The purpose of the demo wasn't to show consistency, but to describe the policy-driven decision/mechanism.

What hit us in the first place (and I think this is what we should fix) is the fact that a brand new nuc-like machine, with a relatively new software stack for spawning VMs (incus / ZFS etc.) behaves so bad it can produce such hiccups for disk IO access...
