[one-users] deploy a vm to a special hosts

[Carlos Martín Sánchez]

Hi,

The core automatically sets the CLUSTER requirement if the VM uses one of
the following:
- an Image stored in a Datastore assigned to a Cluster
- a VNet assigned to a Cluster

You will need to add the Host to the Cluster, or use Images/Vnets available
to that Host.


By the way, I recommend to use NAME inside the requirements. This attribute
is the OpenNebula name for the Host, the one you see in onehost/Sunstone.
On the other hand, HOSTNAME is an attribute returned by the monitorization
probes, and it may not be the same as the Host NAME. This will happen for
example if you have an alias in /etc/hosts, or the short vs FQDN...

Regards
