[one-users] How to configure virtual networks in OpenNebula 4.0

[Javier Fontan]

It seems that you have the context packages installed in the VM but
you are not adding contextualization variables to the VM. When there
are no contextualization parameters the context packages will fallback
to default values. For example, the netmask will be /24.

You can get more information on how to do that manually in the context
doc [1]. From Sunstone you can also check the network
contextualization checkbox when creating the template, that option
will add the variables needed to the template.
