[Xen-users] Xen + Nvidia drivers

["Waeyenbergh, Sven" <Sven.Waeyenbergh@xxxxxxxxxxxxxx>]

Anthony,

that's weird, i did compile my own (xen 2 based) dom0 kernel from source,
then proceeded in installing the nvidia drivers (using the .sh script they 
provide)
Obviously, no pre-made kernel modules were available,
but the script was able to compile its own module (with the correct links in 
/usr/src).
I can't say i've used the graphic features of this system much (it's my server),
but i did not hit any issues with this, works like a breeze.

This is a recipe for disaster.  The nVidia kernel driver has a binary 
layer that it not Xen-ready.  It's very likely that it's going to be 
doing something it's not supposed to do in Xen.

You're out of luck until nVidia releases a Xen driver.  You can also use 
the Open Source driver (or even just Vesa).

This is why binary modules are so evil...
