Default ratio is 20.0, meaning provisioned capacity can be 20 times of the total physical capacity. If the ratio is 10.5, it means provisioned capacity can be 10.5 times of the total physical capacity. A ratio of 1.0 means provisioned capacity cannot exceed the total physical capacity. The ratio has to be a minimum of 1.0. * - ``monkey_patch`` = ``False`` - (Boolean) Enable monkey patching * - ``monkey_patch_modules`` = - (List) List of modules/decorators to monkey patch * - ``my_ip`` = ``10.0.0.1`` - (String) IP address of this host * - ``no_snapshot_gb_quota`` = ``False`` - (Boolean) Whether snapshots count against gigabyte quota * - ``num_shell_tries`` = ``3`` - (Integer) Number of times to attempt to run flakey shell commands * - ``os_privileged_user_auth_url`` = ``None`` - (String) Auth URL associated with the OpenStack privileged account. * - ``os_privileged_user_name`` = ``None`` - (String) OpenStack privileged account username.

Default=False * - ``suppress_requests_ssl_warnings`` = ``False`` - (Boolean) Suppress requests library SSL certificate warnings. * - ``tcp_keepalive`` = ``True`` - (Boolean) Sets the value of TCP_KEEPALIVE (True/False) for each server socket. * - ``tcp_keepalive_count`` = ``None`` - (Integer) Sets the value of TCP_KEEPCNT for each server socket.
