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?
In general no. Usually disks will be enumerated sequentially - thus the
first disk on a sata/scsi/usb/.. bus will be sda, the second will be
sdb, and so on. But libvirt can't guarantee it - the same way you can't
guarantee how a disk is going to be called with real HW.
