[one-users] Tiny Local Business scenario for openNebula

[Carlos Martín Sánchez]

Hi,

OpenNebula can be used for the scenario you describe, even if you are not
going to take advantage of its on-demand cloud features.
It will provide a centralized view and management of your Images and VMs,
what will surely help to administer and monitor your virtualized
workstations.

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).

Knowing that all the VMs will be windows, you may want to configure remote
desktop access to the guest OS instead of VNC.

Regards.
