Hi,

The specific details for the X server crash when booting Xen 3.4.1 dom 0 
pvops kernel are as follows:
[drm] failed to load kernel module "nouveau"
(EE) [drm] drmOpen failed.
(EE) NOUVEAU(0): [drm] error opening the drm
(!!) NOUVEAU(0): Failing back to NoAccel mode

Backtrace:

Fatal server error:
Caught signal 11.  Server aborting

Do I have to update the X server and/or the C library?
