I'm trying to use Xen 3.3.1 w/ the xen-linux mucurial kernel along with the 
Sabtech Swift PCI NTDS driver.  It's a 3rd party module that I have the source 
for, although I can't remember what the license says offhand (taints kernel as 

Basically I need either my dom0 or one of my domUs to be outputting NTDS data 
via 2 of these cards at 50 Hz each.  Initial tests have proven that the driver 
still works when compiled for dom0, but it's not quite meeting our timing 
requirements.  1 second's worth of data is taking around 1.3 seconds, if I 
remember correctly.

I tried to hide the PCI cards from dom0, to see what the behavior is like in a 
domU, but I can't get that to work either.  The pciback new_slot/bind stuff 
appears to work (I don't get errors), but when I try to create my domU, I get 
errors listing other devices that must also be sent to domU (looks like 
everything on that PCI bus)

Do you guys think there's a better chance of getting these boards working on 
domU or dom0?
