1. testbed.py: Run ceos_topo_converger at parse time when use_converged_peers is enabled and the topology YAML has not been pre-converged. This ensures the test fixtures see the converged topology (topo_is_multi_vrf, convergence_data) even when the on-disk YAML was not modified by an earlier add-topo step. 2. vtestbed.yaml: Only enable use_converged_peers for t0 KVM testbeds. Non-t0 topologies (t1-lag, t2, dualtor, etc.) exceed the KVM per-VM VLAN limit (NUM_FP_VLANS_PER_FP=4) when all VMs of the same role are consolidated into one prime device.

ceos_topo_converger now computes max_fp_num based on the actual maximum VLAN count across prime VMs, so enough OVS bridges are created. The computed value is written to the topology YAML and picked up by include_vars (overriding the default max_fp_num=4 from group_vars). This is equivalent to passing -e max_fp_num=<N> on the CLI, but computed automatically. Also restores use_converged_peers for all KVM testbed entries. Co-authored-by: Copilot <[email protected]>
