[one-users] onevm STOP error

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.
