Cole
Thanks for your time. Will try to ask again. Sorry for my bad english :). Will try my best
this time.
I downloaded the code and tried to run the virt-manager.py of off eclipse Pydev IDE.
Ran into some issues, not sure the order but ran
glib-compile-schemas data/*schamas*
ran "python setup.py -install"
after that virt-manager sucessfully came up "with auto connected to lxc:/// and qemu://system"
Now I wanted to understand the code, ran the virt-manager in pdb -debugger.
stepping into the config code found that the "/org/virt-manager/virt-manager/connections/uris"
is already populated with " lxc:/// and qemu://system" value.
but I see that this tuple in dconf DB is only updated by engine code. now wondering how
does config is able to see the " lxc:/// and qemu://system" values.
thanks

Sorry, I'm not really following what you are saying. Can you describe the
problem you are hitting, step by step, and exactly what you are trying to
determine?
Also, take a look at dconf-editor, it's a UI tool for exploring dconf values.
Might explain what you are seeing.
