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 -Avaneendra On Tue, Nov 17, 2015 at 1:37 PM, Cole Robinson <[email protected]> wrote: > On 11/17/2015 11:40 AM, Avaneendra Alugupalli wrote: > > hi Cole > > Thanks for the response. > >> > > > >>The functions that add/remove/list the URIs in config.py are add_conn, > >> remove_conn, list_conn_uris respectively.
