Hisao Taguchi may have found a great idea. Hisao pointed to this
article:

It describes a process to proactively load a different IDE driver to
a Windows XP system before moving it to different hardware. This
absolutely parallels the problem I need to solve – and I gotta
believe I am not alone. I want to P2V a Windows 2003 Server with an
uncooperative system disk driver. I’ve tried virt-p2v, the

old-fashioned ntbackup and restore, and an Acronis trial download.
So far, nothing works – and the whole challenge comes back to that
virtio disk driver not being present in the source physical machine.
If we could come up with a way to proactively install that virtio
driver into a physical Windows Server host before P2Ving it, maybe
we could solve P2V problems worldwide and it would be a huge step
forward.

Subject: [fedora-virt] Restored Windows Server 2003 VM goes black
I tried a P2V migration last week and here might be a better spot to
document the results. I have an aging physical host running Windows
2003 Server and I want to P2V that host in to a libvirt VM. The
physical host uses a Compaq Smart Array 532 Controller with a Compaq
Logical Volume SCSI disk device. The logical volume is a RAID 5 set.
I first tried using the new virt-p2v approach, but haven’t been
successful. So I tried doing it the old-fashioned way. On a RHEL 6.1
host, I built a libvirt Windows 2003 VM from scratch using a virtio
system drive. Then, on the physical host, I ran ntbackup and backed
up all the system drive files to a network share viewable from my
newly provisioned VM. I also backed up the system state. From the
2003 VM, I restored the system drive files and system state and
rebooted.
When rebooting, the VM flashes a couple of POST SeaBIOS lines, then
the console window goes black. No BSOD, just black. Virt-manager
shows the VM is still powered on, but the console window just sits
there, black, until I force the VM to power off. I tried pressing F8
to see if I could get to a Windows boot menu, but this never worked.
I have a hunch something is going on with the new system virtual
drive and the driver for the old system drive.
I can boot the VM from a virtual CD and launch the Windows recovery
console, and from there I can see the Windows installation. The
login uses the new password, so I think the ntbackup – restores did
their jobs. I tried a fixboot and fixmbr, but neither of these did
any good. I tried another ntbackup – restore, this time using an IDE
system drive in my VM (the restore took 50 percent more time than
with virtio), but this also made no difference.
I ended up re-enabling the NIC on the physical host again and now I’m
trying to come up with a plan C. Are there any other ideas I’m not
thinking of?
Thanks
