OK, i found that I don't know how to modify this file correctly, here is my conf ,http://paste.openstack.org/show/158743/

Hey , bothered again! I have installed juno with rdo-allinone in my own CentOS 7 computer successfully. But when I try to install sahara, I met some problem. Here is the steps I have done:

yum install openstack-sahara

after this installed, I run sahara-db-manage --config-file /etc/sahara/sahara.conf upgrade head' and came out

Traceback (most recent call last):
  File "/usr/bin/sahara-db-manage", line 10, in <module>

I don't know what's wrong with my settings. Can you help me?

Sorry, I have solved this problem.I should recreate the private net in the demo user. But a new problem happens, I can not connected to the floating ips. When i ping it, shows host unreachable.

Hi, Today, I reinstalled openstack juno in a single node followed by Quickstart with existing network. I launched an instance successfully. But when I try to associate a floating-ip to this instance, it says no ports available! And I found that the interface of the external network of router 's status is "DOWN". I don't know does this matter. I try to associate floating-ip in command line. Here is the process:

Associated floating IP e0350ad6-3400-4a1b-8f0f-03f2bb8e3e5a

This make the fixed ip and floating ip mapped. However, I can not ping to the actual floating ip. That results in the host is unreachable. I don't know what's wrong with my installation. Bellow is the steps I do to create the public and private network. (my ip is 10.200.45.135, gateway is 10.200.45.254)

neutron router-gateway-clear router1
neutron subnet-delete public_subnet
neutron net-delete public
neutron router-interface-delete router1 private_subnet
neutron subnet-delete private_subnet
neutron net-delete private
neutron router-delete router1

neutron router-create router1
neutron net-create private
neutron subnet-create --name private_subnet private 192.168.100.0/24 --allocation-pool start=192.168.100.224,end=192.168.100.254
neutron router-interface-add router1 private_subnet

neutron net-create public --router:external=True
neutron subnet-create public 10.200.45.135/24 --name public_subnet --enable_dhcp=False --allocation-pool start=10.200.45.224,end=10.200.45.244 --gateway=10.200.45.254
neutron router-gateway-set router1 public

Is there something wrong under my network creation?

WARNING nova.compute.manager [req-c3e07499-bb11-46e1-8703-e437a9faf03e None] While synchronizing instance power states, found 2 instances in the database and 0 instances on the hypervisor. Sorry, I found this warning in compute.log

I hava uploaded the nova-compute.log and scheduler.log. Hope helpful! and the rabbitmq-server is running.

我是使用rdo的allinone安装的juno版本，将openstack部署在了我vmware9的一台Cetnos7的虚拟机上，由于我是新手，所以我完全按照quickstart的安装步骤，但是当我安装好后，启动虚拟机一直卡在孵化中这个状态，不能使用，看了论坛上的一些问题，可是没有找到一些好的解决办法。我的log文件里面也没有显示有什么ERROR，这让我非常的困惑，不知道有谁遇到了同样的问题，或者能够给我提供一个好的解决方法。第一次搭建openstack，还请多多指教。
