I just test with scsi, not virtio. You should be able to get very far along the Windows boot process with extboot. If you just install the LSI driver in Win2k, you can boot up completely. Someone just posted instructions for doing scsi boot with Windows XP assuming you installed the VM from IDE. >> If we can work through the Windows >> issues, this is definitely the right way to go. >> > > So the assembly option rom works with your Win2k??
