Hi,<br>
<br>
I have exactly the same pb, and same needs ...<br>
I start think about a dedicated web service to handle that, but a
shorter (quicker) way to achieve deployments would be nice !<br>
<br>
I will follow this thread for feebacks too<br>
<br>
Best regards,<br>
NB<br>

<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">To further
understand on this OpenNebula, I have setup ONE 4.8 and
testing the Cloud View and see how I can improve my
operation / VM administration.</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">The way user
can create VM in Cloud View is the one I need – user define
the VM name, choose the template (OS), set the memory &
CPU and launch it. Very simple. But unfortunately this only
works with non-persistent image type. In my case, I cannot
use non-persistent image because of the reason stated in #2
and #3 above.</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">So what I think
Cloud View can be improved is:</span></p>

style="">-<span style="font:7.0pt "Times New
Roman"">
</span></span></span><span style="color:#1F497D">Based on
config parameter (oned.conf -> ONE_DEPLOY=Persistent),
when user create a VM, a template should be created and the
image should be cloned as persistent image. This is kinda
same behavior as “Save” VM with only different is the image
persistent yes/no and template spec</span></p>
