driver inside XP-VM can't be installed for virtio-scsi-pci

[udo]

Hi,
just try scsi-passthrough with an win xp vm on 2.1/f32f3f46.

Inside the VM I got the error (translated):

Hardware can't be initialized
Red Hat VirtIO SCSI pass-through controller
The device driver can't be loaded. The driver is possible damaged or be lacking.

And windows wan't to be activated again, because of big hardware changes (not activated yet).

The VM config:

bootdisk: ide0
cores: 1
ide0: oa_sata_r6:vm-305-disk-1
ide2: admin_nfs:iso/virtio-win-0.1-30_120715.iso,media=cdrom,size=44690K
memory: 1024
name: knecht3
net1: virtio=4A:0F:00:D9:0C:98,bridge=vmbr23
ostype: wxp
scsi0: local:305/vm-305-disk-2.raw,size=1G
scsihw: virtio-scsi-pci
sockets: 1

Any hint's ?

where do you get the error message ? windows event log ?
do you use last virtio-scsi driver for windows ?


note: for real scsi-passthrough, you need an iscsi backend (don't works with raw or lvm).
It should be possible in the future, but it need to implement a lio target in kernel, mapping the raw file, and use it through libiscsi.

Hi Spirit,
the error occour in the device manager (driver installation dialog).

windows event log ?

good hint - inside the system log I got an SideBySide error that Microsoft VC80.MFCLOC couln't be found - a micsosoft pages shows that this is an part of c++ http://support.microsoft.com/kb/923014

do you use last virtio-scsi driver for windows ?

Yes - virtio-win-0.1-30. But inside XP isn't the passthrough-driver - only below WXP?!

Ahh,
is that the reason, that I got the same performance on a wk8 (vm-disk on an lvm-iscsi-device) with passthrough and ide?!

I can confirm the issue, exactly the same here.
