Driver won’t install, not compatible

[oliviercailloux]

Describe the bug
Windows XP refuses to install the virtio-fs driver for the “Mass storage” device. Windows says that no compatible driver was found.

To Reproduce

• Install a new Windows XP SP3 guest, shut it down.
• Change the VM definition: add the two xml elements as documented.
• Mount the virtio driver distribution as a CDROM.
• Boot the guest. New devices have appeared. Windows asks for a driver for the Mass storage device.
• Indicate the virtio CD and let Windows search for compatible drivers.
• No compatible driver is found.

Expected behavior
I expect Windows to find a compatible driver.

Host:

• Disto: Debian stable
• Kernel version: 5.10.0-16-amd64 # 1 SMP Debian 5.10.127-2 (2022-07-23) x86_64 GNU/Linux
• QEMU version: 5.2.0 (Debian 1:5.2+dfsg-11+deb11u2)
• QEMU command line: using GUI
• libvirt version: libvirt-daemon:amd64/bullseye 7.0.0-3
• libvirt XML file

VM:

• Windows version: XP
• Which driver has a problem: Virtiofs
• Driver version or commit hash that was used to build the driver: virtio-win-0.1.221.iso.

Additional context
Windows gives me the following ids when I ask for details about the Mass storage device.

Device Instance Id : PCI\VEN_1AF4&DEV_105A&SUBSYS_11001AF4&REV_01\3&267A616A&0&38
Hardware Ids: PCI\VEN_1AF4&DEV_105A&SUBSYS_11001AF4&REV_01,
PCI\VEN_1AF4&DEV_105A&SUBSYS_11001AF4,
PCI\VEN_1AF4&DEV_105A&CC_018000,
PCI\VEN_1AF4&DEV_105A&CC_0180
Compatible Ids: PCI\VEN_1AF4&DEV_105A&REV_01,
PCI\VEN_1AF4&DEV_105A,
PCI\VEN_1AF4&CC_018000,
PCI\VEN_1AF4&CC_0180,
PCI\VEN_1AF4,
PCI\CC_018000,
PCI\CC_0180

Pointing to various specific folders in the virtio CD also fails (same result, no compatible driver).

Installing the Balloon drivers for the memory storage device works with no problem.

Additional question
Is WinSFP required for the driver to install? Is it required that the shared path be reachable and readable? I suppose that these two things cannot help explain why Windows does not find a compatible driver for this device (I expect that those things are only required at a later stage), so to ease debugging I left them aside for now. Is this correct?

Windows XP is not supported, sorry. The oldest supported version is Windows 8.
