Hello OpenNebula folk!

I set my new OpenNebula test config.  
1 server with opennebula (192.168.16.113)  
and 1 server (VM) withe the node (192.168.16.112)

Now i follow the installation frond-end and the Node. (Setup maria-db)  
and make sure that the servers can auto login from the user “oneadmin”

I download the image through the webportal (sunstone) and setup the VM om the host 16.112.

Now I get an Error executing image transfer script: Error copying. What can I do?

```
root@opennebula-01:~# tail -f /var/log/one/1.log 

```

This is the problem, can you check that you can ssh from opennebula-01 to 192.168.16.112 as oneadmin?

The ssh connection works tank you! After this was set, the NFS mounted on the frond-end (113) and node (112) and connect the node as a host.

Now I download from the app store a linux image and set it up as a first VM. The download was completed in the data store, but after set an VM I get this error:

Mon Nov 21 13:59:06 2016 : Error executing image transfer script: Error copying opennebula-01:/var/lib/one//datastores/103/d394b97809d7a1b02d3fdac2fd6793a6 to 192.168.16.112:/var/lib/one//datastores/101/10/disk.0

Can you help me out? thanks in advance 🙂

Can make it have to do with the user “oneadmin”? Because I doesn’t use LDAP and make the user oneadmin manual on the note (VM) because to know the user ID for a good connection for the NFS.

So I can try it with LDAP for the same users with the same ID for a good connection with NFS. Or is the fault elsewhere before I try this option. Thanks for help.

It can be a NFS issue. Can you create the following file as oneadmin in the front-end:

```
 /var/lib/one/datastores/101/10/disk.0
```

Thanks for the info. Let’s try the driver manually, as oneadmin (we assume oned is running as oneadmin?) in the front-end:

/var/lib/one/remotes/tm/shared/clone
