I am not an expert in it, so I may be completely wrong, but at least there is a xenbus
driver, which "attaches to a virtual device on the PCI bus and provides child devices
for the other paravirtual device drivers to attach to." I understand that this will provide
interface only for the other virtual devices, but may be it will also somehow help.

Yes, it is not the new one, but definitely not that old, to allow installation of
Win2k without virtualization

I already wrote to the NI support asking, what can be the cause of the error,
but still no response. Most probably, they'll just tell me that their cards
do not support virtualization
