This is for logical volume download and upload testing.
* using download and upload API under class virStream.
they are functions act as same with download/upload APIs
under class virStorageVol, just different entrance.
* using logical volume specified xml to create volume.
no need to provide volume format.
* check method is the same with dir vol download/upload
cases.
