That said, I don't know what could have caused the app to start up with both qemu:///system _and_ lxc:/// in the connection list, it should only be one or the other (or none, or an error message). You sure you definitely haven't run virt-manager before? FWIW you can test the first-run behavior again by using virt-manager --debug --test-first-run, if you're just trying to figure out how it works - Cole > > On Tue, Nov 17, 2015 at 1:37 PM, Cole Robinson <<a href="mailto:crobinso@redhat.com">crobinso@redhat.com</a> > <mailto:<a href="mailto:crobinso@redhat.com">crobinso@redhat.com</a>>> 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.
