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>
<br><span style="font-family:courier new,monospace">The user john_doe (8) wants to deploy a VM with<br>VM ID : 31<br style="font-family:courier new,monospace"></span><span style="font-family:courier new,monospace">CPU : 2</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">MEMORY : 1024</span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace">DISK : IMAGE ID 15<br> Ubuntu Server<br> 10G</span><br style="font-family:courier new,monospace">
<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>
