[libvirt] How can I get drive_mirror migration progress with non-shared storage on KVM ?

Hi, I want to get a total progress(memory + storage). In none drive mirror migration, I can use virDomainGetJobInfo API to get the total progress. But in drive mirror migration, it seems that I must get file progress by virDomainGetBlockJobInfo and momery progress by virDomainGetJobInfo separately. So does the job status. Is there a way to get the total progress and job status? Thanks.
