Standalone smoke tests validating KV-migration correctness paths before trace replay: full migrate-cache, partial-prefill transfer, and a NIXL-connector variant, each with a runner. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Smoke test for Nixl-based PD-sep migration (NVLink intra-node via UCX).
|
|
#
|
|
# Drops 2 vLLM kv_both NixlConnector instances on GPU 0,1 and runs
|
|
# smoke_test_migrate_cache.py against them with the kv_transfer_params
|
|
# format Nixl expects (only do_remote_decode on src; proxy must forward
|
|
# kv_transfer_params from src's response to dst).
|
|
#
|
|
# Since smoke_test_migrate_cache.py is currently hard-coded for Mooncake
|
|
# (transfer_id + remote_bootstrap_addr), we use a tiny Python in-line
|
|
# variant here that does the Nixl response-forward handshake directly.
