Please, describe the problem here and provide additional information below (if applicable) …  
I just installed OpenNebula according the instruction at the OpenNebula site and am now on the step where I will test the installation according to the instructions at [http://docs.opennebula.org/5.4/deployment/node\_installation/verify.html#verify-installation](http://docs.opennebula.org/5.4/deployment/node_installation/verify.html#verify-installation). I get the following error when trying to instanciate an VM.

**Versions of the related components and OS (frontend, hypervisors, VMs):**  
OpenNebula v5.4.0 running on VirtualBox using Libvirt.

**Steps to reproduce:**  
Follow instruction outlined in the document [http://docs.opennebula.org/5.4/deployment/opennebula\_installation/index.html](http://docs.opennebula.org/5.4/deployment/opennebula_installation/index.html) and run the test outlined in the page: Verify Installation.

BTW: There is no permission issue on the folder /var/lib/one/datastores/103/2/ as I can create files with he user oneadmin.

Provide the current output of

> onedatastore list

It looks like all your datastores are shared, can nebula2.dasilva.network access front1.dasilva.network:/var/lib/one/datastores?

Consider basing your test setup on [GitHub - marcindulak/vagrant-opennebula-tutorial-centos7: Configures OpenNebula cluster using libvirt/kvm nested virtualization in Vagrant](https://github.com/marcindulak/vagrant-opennebula-tutorial-centos7) - it uses kvm all way down, and nfs as shared storage.

Thank you for your answer.  
The nodes can access the datastores as they are shared through NFS. Please see prove bellow:

**Create a test1 file on nebula2:**

oneadmin@nebula2:~/datastores/103/3$ ls -la  
totalt 8  
drwxrwsr-x 2 oneadmin oneadmin 4096 sep 17 13:18 .

oneadmin@nebula2:~/datastores/103/3$ touch test1  
oneadmin@nebula2:~/datastores/103/3$ ls -la  
totalt 8  
drwxrwsr-x 2 oneadmin oneadmin 4096 sep 17 13:19 .  
drwxr-sr-x 3 oneadmin oneadmin 4096 sep 17 13:18 …  
---------- 1 oneadmin oneadmin 0 mar 15 1972 disk.0  
-rw-rw-r-- 1 oneadmin oneadmin 0 sep 17 13:19 test1

**Remove the file the file on front1.**

oneadmin@front1:~/datastores/103/3$ ls -la  
totalt 8  
drwxrwsr-x 2 oneadmin oneadmin 4096 sep 17 13:19 .  
drwxr-sr-x 3 oneadmin oneadmin 4096 sep 17 13:18 …  
---------- 1 oneadmin oneadmin 0 mar 15 1972 disk.0  
-rw-rw-r-- 1 oneadmin oneadmin 0 sep 17 13:19 test1  
oneadmin@front1:~/datastores/103/3$ rm test1  
oneadmin@front1:~/datastores/103/3$ ls -la  
totalt 8  
drwxrwsr-x 2 oneadmin oneadmin 4096 sep 17 13:21 .  
drwxr-sr-x 3 oneadmin oneadmin 4096 sep 17 13:18 …  
---------- 1 oneadmin oneadmin 0 mar 15 1972 disk.0  
oneadmin@front1:~/datastores/103/3$ whoami  
oneadmin  
oneadmin@front1:~/datastores/103/3$ pwd  
/var/lib/one/datastores/103/3

**Verify the removal of test1-file on nebula2:**  
oneadmin@nebula2:~/datastores/103/3$ ls -l  
totalt 0  
---------- 1 oneadmin oneadmin 0 mar 15 1972 disk.0  
oneadmin@nebula2:~/datastores/103/3$ whoami  
oneadmin  
oneadmin@nebula2:~/datastores/103/3$ pwd  
/var/lib/one/datastores/103/3

Bellow are the /etc/fstab entry for each nodes datastore:

_front1_  
nas.dasilva.network:/ImageDatastore /var/lib/one/datastores nfs soft,intr,rsize=32768,wsize=32768 0 0

_nebula1 and nebula2_  
nas.dasilva.network:/ImageDatastore /var/lib/one/datastores nfs soft,intr,rsize=32768,wsize=32768 0 0

And I can do ssh without the use of a password to and from each host  
front1 \<-\> nebula1  
front1 \<-\> nebula2

Can you list permissions and sizes under the datastores?

> tree -ps /var/lib/one/datastores/

“---------- 1 oneadmin oneadmin 0 mar 15 1972 disk.0” looks strange.

Is ntp working on all hosts?

Hi!  
I tried to change to a different NFS-server to see if that was the issue and tried the same thing, but I got the same error.

Here is the output you asked for:

```
/var/lib/one/datastores/
├── [drwxr-xr-x 4096] 0
│ ├── [drwxrwxr-x 4096] 0
│ └── [drwxrwxr-x 4096] 7
├── [drwxr-xr-x 4096] 1
└── [drwxr-xr-x 4096] 2

5 directories, 0 files

```

The NTP is working on all nodes. Here are the output of the ntpstat which are similar on all nodes (front1,nebula1 and nebula2):

```
synchronised to NTP server (192.36.143.130) at stratum 2 
   time correct to within 30 ms
   polling server every 512 s

```

Here is the /etc/export file from the NFS-server

`/mnt/vm-images/datastores 192.168.1.0/24(rw,sync,no_subtree_check,root_squash)`

Here is the /etc/fstab file used on the machines (front1,nebula1 and nebula2), which all mount the same share.

`192.168.1.2:/mnt/vm-images/datastores /var/lib/one/datastores nfs soft,intr,rsize=32768,wsize=32768 0 0`

Here is the last log message from oned.log when I re-tried to create another VM on the “new” NFS-server for reference

How the output looks like after there is an image downloaded into the datastore?

Try also to experiment with no\_root\_squash instead ([https://github.com/marcindulak/vagrant-opennebula-tutorial-centos7/blob/dbf8ec68593eebd5b8908c0da74583b0a5aa8f5f/Vagrantfile#L225](https://github.com/marcindulak/vagrant-opennebula-tutorial-centos7/blob/dbf8ec68593eebd5b8908c0da74583b0a5aa8f5f/Vagrantfile#L225)) - if this turns out to the the problem, it is worth investigating what opennebula really does on nfs.

Hi!  
I turned off IPv6 and the firewall on all machines, including the Virtualbox host, modified the /etc/export to have no\_root\_sqaush, restarted NFS-server and all the VM:s.  
I downloaded the ttylinux - kvm from Apps gave the template a different name (ttylinux1 - kvm).  
I Instantiated it and now I get a different error message.

```

Bellow is the output of the tree-command.

```

I also have the KVM module loaded on all the machines:

See if the suggestion from [https://forum.opennebula.io/t/test-vm-trouble](https://forum.opennebula.io/t/test-vm-trouble) helps, but I would recommend to switch to kvm, as in the details of my first post. Also, there is no point of working with ttylinux, in my experience networking on ttylinux recently is not working out of the box, use the marketplace centos7 or other full linux instead.

Good news! I got it working now, by just editing the /etc/oned.conf files and changing from KVM to QEMU according to the instruction in the link of your previous reply.  
Thank you for your patience and support.

Just a question: what OS your frontend and worker nodes use?

[https://docs.opennebula.org/5.4/deployment/open\_cloud\_storage\_setup/fs\_ds.html](https://docs.opennebula.org/5.4/deployment/open_cloud_storage_setup/fs_ds.html) contains a passage “In case the files must be read by root the option no\_root\_squash must be added”, which is not clear to me. Which files are read by root?  
Is the no\_root\_squash requirement limited to CentOS 7 only [https://www.redhat.com/archives/libvirt-users/2016-April/msg00019.html](https://www.redhat.com/archives/libvirt-users/2016-April/msg00019.html)? The problem may be worth investigating by someone among the developers.

The host is running Linux Mint 18.2. The virtual machines running on VirtualBox ( Version 5.1.28 r117968 (Qt5.5.1) ) which OpenNebula is installed on are as follow: one front-end and two nodes, which all are running the latest Ubuntu 16.04 with all the latest security fixes.
