[et-mgmt-tools] multiple connections in virt-manager first draft now on tip

[Hugh Brock]

Hi all.

I have just committed the first cut at a UI for handling multiple 
connections from a single manager window in virt-manager. Opening a new 
connection with File->Open Connection... will now display that 
connection and its guests (if any) in a tree layout in the manager 
window. The "new" button is gone, in favor of a right-click option for 
creating guests for a particular connection. If you click the 
expand/collapse arrow to collapse a connection, virt-manager will avoid 
polling that connection for resource updates until you expand the arrow 
again (handy for avoiding excessive network traffic in the remote 
connection case).

Things that still need to be dealt with:

1. I have temporarily disabled restoring guests from the UI. It's 
necessary to specify a connection when restoring a guest, and this 
brings up issues around how to choose that connection and the whole 
guest checkpointing question.

2. There should really be a little "new" or "create" button on each 
connection line along with the right-click menu.

3. We should store connection info in gconf rather than having them 
vanish on disconnection. This way when you start virt-manager all your 
connections would come up inactive, and actually connect only when you 
activate them.

4. Creating a new guest still works only on local connections. Guest 
creation for remote connections depends on resource discovery which we 
still haven't worked out yet.

Please give the new UI a spin and let me know if you find anything 
broken. In particular, I haven't tested it with remote connections, 
although (aside from creating a guest) there is no reason it shouldn't work.

Enjoy,
--Hugh
