Hi guys, In virsh, in the cmdSchedinfo() function, there's a block of code using printf instead of vshPrintf(): for (i = 0; i < nparams; i++){ switch (params[i].type) { case VIR_DOMAIN_SCHED_FIELD_INT: printf("%-15s: %d\n", params[i].field, params[i].value.i); break; case VIR_DOMAIN_SCHED_FIELD_UINT: printf("%-15s: %u\n", params[i].field, params[i].value.ui); break; case VIR_DOMAIN_SCHED_FIELD_LLONG: printf("%-15s: %lld\n", params[i].field, params[i].value.l); break; case VIR_DOMAIN_SCHED_FIELD_ULLONG: printf("%-15s: %llu\n", params[i].field, params[i].value.ul); break; case VIR_DOMAIN_SCHED_FIELD_DOUBLE: printf("%-15s: %f\n", params[i].field, params[i].value.d); break; case VIR_DOMAIN_SCHED_FIELD_BOOLEAN: printf("%-15s: %d\n", params[i].field, params[i].value.b); break; default: printf("not implemented scheduler parameter type\n"); } } These should be vshPrintf() shouldn't they?
