Hi, Migrate feature have a restrict: target domain iothreads count must match source The relevant code as follows: ------------------------------------ if (src->niothreadids != dst->niothreadids) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, _("Target domain iothreads count %zu does not " "match source %zu"), dst->niothreadids, src->niothreadids); goto error; } ------------------------------------ I tried to remove the restrict, and perform migrate in that case: "target domain iothreads count does not match source" , Anything is normal! So, can we remove the restrict to support this case?
