Thanks all of you for your help.
One more question regarding  vhost-user-blk-pci type device,  how to identify a vhost-blk disk in QEUM VM ?  for example, disk name looks like vda,vdb,..., but that some application in VM want to detect  that a certain entry is really the device it is waiting for. Specific for windows , they always show as disk 0, 1, 2….etc
Is there any way to identify those disk with each other in VM?
