<br>
<br><font size="3">Hi,<br>
<br>
We don't have any tool to manage the workflow, but OpenNebula can be easily
tweaked with a few shell script lines.<br>
The scenario you describe can be achieved using hooks [1] in the following
way:<br>
<br>
1 - After a VM creation (or a Template instantiation), a VM "on create"
hook can be triggered to hold the VM (the scheduler ignores VMs in this
state) and send that notification email.<br>
The hook can query OpenNebula for details about the user, the VM or any
other resources used in the requested VM like Images or VNets. That email
could look like this:<br>
</font><font face="Courier" size="3"><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</font><font size="3"><br>
<br>
2 - If the administrator decides to approve the request, then he simply
has 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
such as procmail to enable or delete the VM after reciving a "yes/no"
email reply from the administrator.<br>
<br>
3 - Another hook can be triggered when the VM reaches the running state.
This one will send an email to the owner user with the login instructions,
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
sqlite DB, a new table in OpenNebula's DB, or even use the email as the
OpenNebula username.<br>
<br>
This is a basic configuration to get you started, but the hook mechanism
can 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
would be denied without bothering the administrator with more emails<br>
- Sunstone tuning [4] : you could modify sunstone to adapt it to your needs.
Views can be configured to show only certain tabs, or maybe hide some buttons.
You could even include a new text input box that would allow users to include
a personalized message for the administrator each time a VM is created.
The "on create" hook can look for that attribute in the VM template
and add it to the email.<br>
<br>
Best regards,<br>
Carlos.<br>
