From 208e5227669ec8de02bd253626566fd72eb3090c Mon Sep 17 00:00:00 2001 From: Arun Menon Date: Thu, 18 Sep 2025 20:53:33 +0530 Subject: [PATCH] migration: push Error **errp into loadvm_postcopy_handle_listen() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This is an incremental step in converting vmstate loading code to report error via Error objects instead of directly printing it to console/monitor. It is ensured that loadvm_postcopy_handle_listen() must report an error in errp, in case of failure. Reviewed-by: Fabiano Rosas Reviewed-by: Daniel P.
