Which NFS version are you using? I had troubles with some distributions using NFS4, which had some permission issues. I read that performance-wise version 3 and 4 are alike so I recommend you to add the following:
nfsvers=3 to your exports file: /srv/cloud 192.168.1.6(rw,no_root_squash,anonuid=0,anongid=0,sync,nfsvers=3) Hope it helps, Samuel.
