I am not an expert in d-bus nor virt-manager. All I am trying to test is some SAM features which require setting up of guests through virt-manager. I tried many times using rhel 7 boxes provisioned via beaker and got the same issue as I explained in this email before. I am looking for a solution (or a workaround) to make virt-manager work in my rhel 7 box. > Martin > > >>> | -- > >>> | Suresh Thirugnanasambandan| Sr. Quality Engineer | irc: sthirugn > >>> | > >>> | > >>> > > > -- Suresh Thirugnanasambandan| Sr. Quality Engineer | irc: sthirugn _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
