/vm-rebalance Skill

Orchestrate VM migrations across OpenShift cluster nodes for load balancing, maintenance, and resource optimization. Supports manual and automatic rebalancing with live migration (zero downtime) and cold migration (brief downtime) strategies.

Implementation: Uses KubeVirt's VirtualMachineInstanceMigration API for live migrations and node affinity for cold migrations.
