Worked on enhancing virtual machine migration observability within the xapi-project/xen-api repository, focusing on backend development and distributed systems using OCaml. Developed granular tracing around the VM pause phase to provide deeper insight into migration events and introduced a with_tracing helper to ensure proper span lifecycle management, even in error scenarios. Refactored trace propagation by improving traceparent handling, allowing orphaned spans to be correctly associated with their parent traces. These changes improved debugging and operational visibility, enabling faster root-cause analysis and reducing downtime during migrations. The work demonstrated a strong emphasis on observability and system programming in virtualization environments.
