One virtual machine runnning on Xen host experienced 'Stale NFS file handle' problems and I can't explain it while there is no NFS mount present.
The problem occurs when listing the content on a specific directory:
$ ls -la ls: cannot access xxx: Stale NFS file handle
The following command returns nothing:
mount -t nfs
