[github-actions]

👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can do one of these:

• Add ready label to the PR
• Enable auto-merge.

🚀

seems lost the original parallel_config check?

    if (config.distributed_executor_backend is not None
            and config.distributed_executor_backend != "ray"):
        logger.warning(
            "%s is not supported on XPU, fallback to ray distributed executor "
            "backend.", config.distributed_executor_backend)
        config.distributed_executor_backend = "ray"

I think that function _verify_and_get_parallel_config is not called.

[yma11]

This check should be included for xpu platform. The call stack seems get broken in commit.
