So I guess that your /var/lib/virt-v2v/virt-v2v.db or /etc/virt-v2v.conf doesn't contain an OS matching this. However my copy of virt-v2v.db certainly *does* have it: <app os='windows' major='5' minor='2' arch='x86_64' name='virtio'> <path>/usr/share/virtio-win/drivers/amd64/Win2003</path> </app> I can't remember how this is added. Maybe you need to install the virtio-win drivers? > Iam running virt-v2v on Fedora 19. OVirt is 3.3.0 version.. You probably want to ask Matt Booth about this ... Rich.
