Hey,

for now I've prepared an RPM which can be installed using the edit-node
tool (see below). After editing an ISO, install it, login, drop to shell
using F2 and run /usr/bin/ovirt-config-setup to run the new TUI.
The TUI is not very functional yet.
- It runs and picks up the network config defined in /etc/default/ovirt.
In general is the TUI generally manipulating the defaults file (there is
one mechanism for it, which is working), and afterwards (component
specific) applying these configurations.
- All Pages can be displayed
- It has been tested over ssh
- It reacts to screen resizes (try below 80x23)
- The mouse can be used to navigate

It also offers the following functionality:
- Easy creation of pages and dialogs
- Simple model+changes based approach (initial model, and UI adds
changes to this)
- UI can be updated through other threads
- UTF8 support

Additionally it has ton's of issues but it's one a good way.
