[one-users] OpenNebuka Hosted-VLAN support

[Alberto Picón Couselo]

As you mention, we have implemented a static vlan configuration for the 
moment.

We are glad to know that these issues could be addressed in Opennebula 
v3.2.

Please, consider our help for testing whatever you may need.

Thank you very much for your help and such a great product,
Best Regards,
Alberto Picón
