In this case unixctl_server_create() will still place it into ovs_rundir(). So, you need to have: abs_unixctl_path = unixctl_path ? abs_file_name(ovn_rundir(), unixctl_path) : get_abs_unix_ctl_path(); Another and, probably, better approach is to add an optional 'path' argument to get_abs_unix_ctl_path() so it might call abs_file_name() for us. so it will look like: abs_unixctl_path = get_abs_unix_ctl_path(unixctl_path); However, this seems like existing issue for all the OVN processes. None of the ovn applications checks if 'unixctl_path' is an absolute path or not. > + } > + > + int error = unixctl_server_create(abs_unixctl_path, &server); > + if (!unixctl_path) { > + free(abs_unixctl_path); > + } > + > if (error) { > ctl_fatal("failed to create unixctl server (%s)", > ovs_retval_to_string(error)); >

Thanks Ilya and Dumitru. I addressed this in the v2. Request to take a look at it.
