Goal

Understand the stuntime of localnet networking during cross-cluster live migration, explain it in an RCA document, and propose how to improve it.

User Stories

As a user migrating a VM between sites,
I want the stuntime to be as little as if I was migrating within a cluster,
so my application and my clients do not suffer any unexpected issues.

<List of things not included in this epic, to alleviate any doubt raised during the grooming process.>

We assume that due to the way OVN Kubernetes handles live-migration with localnet, the stuntime during migration between clusters will be considerably higher than within a cluster, due to lack of any "handover".
