When creating a new machine under advanced options all I see on the drop down
menu is the following:

* Virtual network default 'NAT' <- selected
* Host eth0 (Not bridged) <- greyed - not selectable
* Host eth1 (Not bridged) <- greyed - not selectable
* Host lo (Not bridged) <- greyed - not selectable
* Host virbr0 (Not bridged) <- greyed - not selectable
* Host vnet0 (Not bridged) <- greyed - not selectable
* Host vnet1 (Not bridged) <- greyed - not selectable
* Host vnet2 (Not bridged) <- greyed - not selectable
* Host vnet0 (Not bridged) <- greyed - not selectable
Specify shared device name <- black - selectable


If I select <Specify shared device name> then, and only then, a text box with
the label 'Bridge name:' appears.

My memory is always suspect but I seem to recall that the defined bridge, br0'
was explicitly listed as an available choice in a previous version of
virt-manager and not obscured in this fashion.  The term <Specify shared
device name> does not, in my mind, equate to the word 'bridge'.  Given the
text box label that appears only when one selects <Specify a shared device
name> evidently indicates that this selection only expects a bridge one
wonders why such a vague phrase is used instead of something like <Specify a
bridge(d) device name>.
