Re: [Xen-users] Problem with VT-d on Mainboard Intel DQ45CB

Hello James,

did you do the following (it's metioned in my howto file)?

>make linux-2.6-xen-config CONFIGMODE=menuconfig

This compiles the PCI-device backend driver fixed into the kernel.
I tried to use the module but did not succeed in loading the module and 
activating the PCI backend hiding that way. However, compiling it fixed into 
the kernel works for me.

Regards,

Franz
