Ok, I think this should also be fine.<br>

Because it could not write the file<br>
/srv/cloud/one/var//images/e0561a492c9aaac280479f2f0d85dcced9156fbf as<br>
the log file you have posted shows. Is the oneadmin user able to<br>
write into this folder?<br>
<br>
Also check your configuration, this // is not normal (but usualy<br>
should not be a problem). Eventually you have set / at the end of<br>
the paths in your oned.conf, remove it.<br>
<br>

<br>
You need to have the folder /srv/cloud/one/var/images/ also<br>
available on the cluster node and there the user oneadmin (or<br>
eventually libvirtd) needs to be able to write into it.<br>
<br>
<br>

The cluster node (or libvirtd) needs to be able to write into this<br>
folder. It looks like it is running as root, so you need to allow<br>
root to write to the NFS file system, this needs to be adjusted on<br>
the NFS server in /etc/exports (see 'man exports' for details).<br>

Hi,<br>
<br>
We don't have any tool to manage the workflow, but OpenNebula can be easily<br>
tweaked with a few shell script lines.<br>
The scenario you describe can be achieved using hooks [1] in the following<br>
way:<br>
<br>
1 - After a VM creation (or a Template instantiation), a VM "on create" hook<br>
can be triggered to hold the VM (the scheduler ignores VMs in this state)<br>
and send that notification email.<br>
The hook can query OpenNebula for details about the user, the VM or any<br>
other resources used in the requested VM like Images or VNets. That email<br>
could look like this:<br>
<br>
The user john_doe (8) wants to deploy a VM with<br>
VM ID : 31<br>
CPU : 2<br>
MEMORY : 1024<br>
DISK : IMAGE ID 15<br>
Ubuntu Server<br>
10G<br>
<br>
2 - If the administrator decides to approve the request, then he simply has<br>
to enable that VM. For a denied request, the VM can be deleted.<br>
This could be done manually, using the CLI or Sunstone.<br>
I guess it shouldn't be too difficult to configure a mail delivery agent<br>
such as procmail to enable or delete the VM after reciving a "yes/no" email<br>
reply from the administrator.<br>
<br>
3 - Another hook can be triggered when the VM reaches the running state.<br>
This one will send an email to the owner user with the login instructions,<br>
including VM details like the assigned IP.<br>
You have to come up with a way to store the user's email. Maybe a small<br>
sqlite DB, a new table in OpenNebula's DB, or even use the email as the<br>
OpenNebula username.<br>
<br>
This is a basic configuration to get you started, but the hook mechanism can<br>
be combined with:<br>
- ACLs [2] : you may want to fine-tune the allowed user actions<br>
- usage quotas [3] : after certain limits, the new VM creation requests<br>
would be denied without bothering the administrator with more emails<br>
- Sunstone tuning [4] : you could modify sunstone to adapt it to your needs.<br>
Views can be configured to show only certain tabs, or maybe hide some<br>
buttons. You could even include a new text input box that would allow users<br>
to include a personalized message for the administrator each time a VM is<br>
created. The "on create" hook can look for that attribute in the VM template<br>
and add it to the email.<br>
<br>
Best regards,<br>
Carlos.<br>
