[one-users] Incorrect netmask on virtual machines

[Javier Fontan]

I suppose you already have contextualization package installed in you
VM as you are getting the correct IP.

The problem most probably comes because the VM (template) does not
have a CONTEXT section with network information. If you are using
Sunstone and OpenNebula 4.2 you can add that information checking
Context->Add network contextualization in the template creation
wizzard.
