[Fedora-xen] problem to load nfs with initrd

[Thorsten Scherf]

Hi,

I tried to access a nfs based system root within a xen guest. When the
initrd loads the nfs module, it fails with the following error:

Mounting sysfs filesystem
Creating /dev
Creating initial device nodes
Setting up hotplug.
Creating block device nodes.

no problems with the other modules build into the initrd. 
kernel version is  2.6.17-1.2630.fc6xen.

ideas?

Thanks,
Thorsten
