Re: [Xen-devel] VGA passthrough nVidia NVS 295

[Helmut Wieser <helmut.wieser@xxxxxxxx>]

Hi Tobias,

Yes, I get the exact same error. Googling didn't reveal much. I don't 
get this error in Windows XP though, but I do get other issues.
None are concise, so I think my Xen / Kernel version combo is unstable, 
or my hardware is.
I'm running on a Intel 5520 chipset with dual E5620 Xeon and a Nvidia 
Quadro NVS 295, G98.
Were you more successful in passing through to a Linux domU?

The chipsets and CPUs are well supported, only the graphics card didn't 
show up anywhere.
regards,
Helmut
