Re: [Xen-devel] Vt-d not working with 3.4.1

["Mr. Teo En Ming (Zhang Enming)" <enming.teo@xxxxxxxxxxxxxxx>]

Hi,

I saw this posting by Boris.

http://article.gmane.org/gmane.comp.emulators.xen.devel/61143

Perhaps the Xen dom 0 pvops kernel I am using is too new (2.6.30-rc3), 
and the NVIDIA driver I am using does not support it.
