hi!
i've got a very weird problem, when using root_nfs in domU's.
i'm currently running cownfsd, which i am able to use locally and
remotely via
mount -t nfs
but, when using this share in a domU, it doesn't mount as root.
domU shows following bootmsg:

as said, mount works:

i don't know what to setup in the domU's kernel, to get this working.
If someone of you does have any idea about this error?
I'm pretty sure that my settings /etc/xen/mosixen settings are right, as
this machine works without changing the settings, but with kernel-nfsd
at dom0 as server.
Thanks
