Hello Aline,

I refer to the latest version of the
User Interface Design Specification - Kimchi, 2014-12-23 (aka UI Design Spec)
which defines the following structure of functionalities:

Host (second level navigation via panel areas)
   Performance (System Statistics)
   Basic Information
   Repositories
   Debug Report
   Software Updates

Guests
    no second level functionalities

Templates
    no second level functionalities

Storage
    no second level functionalities

Networks
    no second level functionalities

Administration (second level navigation via collapse/expand)
   Firmware Update
   SEP Configuration
   Power Options
   Configuration Backup
   Network Configuration
   SAN Adapters
   Sensor Monitor



Problem Statement

We already decided to move all Administration functionalities to Host (currently not updated in the UI Design Spec).

We are currently facing the following problems:
1) Host now contains 12 second level functionalities, all other (Guests, Templates, ...) none.
     We need to introduce a second level navigation for Host other than collapse/expand
2) The navigation bar elements Storage and Network (refering to Virtualization) also exist in the Host context.
     This might confuse the user.



Proposal

The described problems can be solved with the following changes:

1) Introducing a second level navigation
2) Changing the structure of functionalities as follows:

Host
   Performance (System Statistics)
   Basic Information
   Repositories
   Debug Report
   Software Updates
   Firmware Update
   SEP Configuration
   Power Options
   Configuration Backup
   Network Configuration
   SAN Adapters
   Sensor Monitor

Virtualization
   Guests
   Templates
   Storage
   Networks

Containers (future extension)
   to be defined



Let's start a discussion on this.

Kind regards
Jan
