The vendor specific designator in the Device Identification VPD page has two problems: 1. It defaults to the BlockBackend name (-drive id=...), which everyone expected to be a host detail that the guest never sees 2. With -blockdev based setups it defaults to an empty string; if this default is used with more than one disk, the guest OS will interpret this as a single multipath disk. We can address problem 2 immediately, and start running the deprecation clock for problem 1.
