Hello list!:

I'm having a problem with NFS under a domU with fedora core 3 / xenU

When the nfs daemon is started (or restarted):

# service nfs restart
Shutting down NFS mountd:                                  [  OK  ]
Shutting down NFS daemon:                                  [  OK  ]
Shutting down NFS quotas:                                  [  OK  ]
Shutting down NFS services:                                [  OK  ]
Starting NFS services:                                     [  OK  ]
Starting NFS quotas:                                       [  OK  ]
Starting NFS daemon:                                       [  OK  ]
Starting NFS mountd:                                       [  OK  ]
Starting RPC idmapd: FATAL: Module sunrpc not found.
FATAL: Error running install command for sunrpc

Trying to mount the shared resources:

# mount -t nfs4  w.x.y.z:/download /root/nfs
Warning: rpc.idmapd appears not to be running.
         All uids will be mapped to the nobody uid.
mount to NFS server 'w.x.y.z' failed.

I tried the proposed solutions here:


and here:


In the domU /var/log/messages I can see:

Nov 11 08:24:06 ltskbunk rpc.idmapd: nfsdreopen: Opening
'/proc/net/rpc/nfs4.idtoname/channel' failed: errno 2 (No such file or
Nov 11 08:24:06 ltskbunk rpc.idmapd: nfsdreopen: Opening
'/proc/net/rpc/nfs4.nametoid/channel' failed: errno 2 (No such file or

I'm guessing that there is not a xen issue. But I wonder if someone here
can give some light.
