Thanks.
It may be correct.

Thanks.
I want to review around these codes.

VBD processes in domain0 runs as xvd threads.
These threads names "xvd [Domain name] [Major Number]:[Minor Number]".
So, I show same name inelligibly.
In addition, I think that total Information for each domain is added optionally.
Therefore, its informatin is needed in such time.
