Description of problem:
virsh domjobabort displays error information for aborting domain save job, in fact, domjobinfo and domjobabort operations support migrate and save job, however, libvirt source codes exist hard code for migration in libvirt-0.8.4 tar package:

 ......

 5039 static int
 5040 qemuDomainWaitForMigrationComplete(struct qemud_driver *driver, virDomainObjPtr vm)
 5041 {
 ......

 5150         case QEMU_MONITOR_MIGRATION_STATUS_CANCELLED:
 5151             priv->jobInfo.type = VIR_DOMAIN_JOB_CANCELLED;
 5152             qemuReportError(VIR_ERR_OPERATION_FAILED,
 5153                             "%s", _("Migration was cancelled by client"));
 5154             break;
 5155         }
 ......


Whether we may add a QEMU_MONITOR_SAVE_STATUS_CANCELLED, and then:

          case QEMU_MONITOR_SAVE_STATUS_CANCELLED:
              priv->jobInfo.type = VIR_DOMAIN_JOB_CANCELLED;
              qemuReportError(VIR_ERR_OPERATION_FAILED,
                              "%s", _("Saving was cancelled by client"));
              break;
          }

or giving variable to for Migration and Saving.
