[Qemu-discuss] Setting disk description strings

[DS Jstc]

I'm trying to fool some Windows software into thinking it's running on 
bare metal.  Having successfully done it in VirtualBox, I believe the 
only thing standing between me success, is the way the Qemu disk driver 
describes itself to the OS.  In VirtualBox, I'd just set the following 
extra data and be away to the races:

    VBoxManage setextradata WIN10-STEALTH 
"VBoxInternal/Devices/ahci/0/Config/Port0/ModelNumber" "SEAGATE ST3750525AS"
    VBoxManage setextradata WIN10-STEALTH 
"VBoxInternal/Devices/ahci/0/Config/Port0/SerialNumber" "a123456789"
    VBoxManage setextradata WIN10-STEALTH 
"VBoxInternal/Devices/ahci/0/Config/Port0/FirmwareRevision" "1.23"

Is there any way to similarly override the descriptive reporting for the 
Qemu disk driver?  Could I just manually use a different windows driver?

Alternately, I have a SATA drive that I can dedicate to this VM (but not 
a spare SATA controller).  I've successfully hooked it up as a raw block 
device and booted from it, like this:

    <disk type='block' device='disk'>
      <driver name='qemu' type='raw'/>
      <source dev='/dev/sdb'/>
      <target dev='sda' bus='sata'/>
      <boot order='2'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

It doesn't help.  If I look at the device details in the Windows 10 
guest, it still has a "bus reported device description" of "QEMU 
HARDDISK".  I'd assume that's because I'm using the 'qemu' driver in 
libvirt, and that's what the hypervisor is returning to the guest's disk 
driver.  Is there another qemu-side driver I can use for a passed 
through raw device?

Apologies if this is documented somewhere.  I've searched quite a bit 
and not found anything that seemed relevant -- what should I be reading?
