[one-users] Why host is mandatory in the onevm deploy command ?

[Daniel Molina Aranda]

Hi Philippe,

The "onevm deploy" command will force the virtual machine deployment
ignoring the scheduler decision, so that you have to specify the host where
you want the virtual machine to be deployed.

If you want to use the cluster option, you have to specify the cluster name
in the "REQUIREMENTS" section of the virtual machine template. This value
will be used by the scheduler to choose a host of that cluster.

REQUIREMENTS = "CLUSTER = \"testing\""


For more information
- REQUIREMENTS section:
http://www.opennebula.org/documentation:rel2.0:template#placement_section
- Clusters and Hosts:

Hope this helps.
