So I tried adding another drive, a virtio one, (a new 100MB file at
host side) to the virtual machine and rebooting.
A first problem is that Windows does not detect the new device upon
boot or Add Hardware scan.
Check PCI devices with "info pci". You must have "SCSI controller: PCI
device 1af4:1001" device reported.
It's not there. Does this make it a KVM bug?
I'm attaching the PCI32.EXE output at the bottom of this email
BTW I would probably be able to switch to virtio anyway on this
installation of Windows 2003, if I knew the way to insert the viostor
driver into the windows boot image (windows's initrd), because if I set
the first disk hda as virtio then kvm really makes it virtio (so maybe
it's a configuration with one IDE and one virtio that does not work in
KVM) and Windows bluescreens at boot. However I don't know how to insert
the viostor driver in the windows boot image. Any suggestions?
Here is the kvm commandline (it's complex because it comes from
libvirt):
