  "message": "backends/tpm: Propagate vTPM error on migration failure\n\n- When migration of a VM with encrypted vTPM fails on the\n  destination host, (e.g., due to a mismatch in secret values),\n  the error message displayed on the source host is generic and unhelpful.\n- For example, a typical error looks like this:\n  \"operation failed: job \u0027migration out\u0027 failed: Sibling indicated error 1.\n  operation failed: job \u0027migration in\u0027 failed: load of migration failed:\n  Input/output error\"\n- Such generic errors are logged using error_report(), which prints to\n  the console/monitor but does not make the detailed error accessible via\n  the QMP query-migrate command.\n- This change, along with the set of changes of passing errp Error object\n  to the VM state loading functions, help in addressing the issue.\n  We use the post_load_errp hook of VMStateDescription to propagate errors\n  by setting Error **errp objects in case of failure in the TPM backend.\n- It can then be retrieved using QMP command:\n  {\"execute\" : \"query-migrate\"}\n\nBuglink: https://issues.redhat.com/browse/RHEL-82826\n\nReviewed-by: Stefan Berger \u003cstefanb@linux.ibm.com\u003e\nReviewed-by: Daniel P.
