Hi,<br><br>OpenNebula can be used for the scenario you describe, even if you are not going to take advantage of its on-demand cloud features.<br>It will provide a centralized view and management of your Images and VMs, what will surely help to administer and monitor your virtualized workstations.<br>
<br>OpenNebula can use the same computer as the front-end and host, the only thing to keep in mind is that you need to use the shared storage transfer manager [1] (the front-end and the hosts are "sharing" the same storage).<br>
<br>Knowing that all the VMs will be windows, you may want to configure remote desktop access to the guest OS instead of VNC.<br><br>Regards.<br><br>[1] <a href="http://opennebula.org/documentation:rel3.0:sfs">http://opennebula.org/documentation:rel3.0:sfs</a><br>

Hi Ben.<br>
I appreciate your answer.<br>
<br>
I was expecting to be able to install kvm, sshd, and openNebula on the<br>
same hardware. As I would not need to provide many different<br>
technologies.<br>
I think that I would have maybe 4 VM at the same time, but the virtual<br>
processor will be most of the time sleeping.<br>
<br>
Will this be in some software related conflict ? Or your<br>
recommendation is due to the load ?<br>
<br>
It sounds that the method you describe, involves the same procedures<br>
as installing openNebula.<br>
<br>
Kind regards,<br>
Diego<br>
<br>
