Provider Network subnet issue

asked 2016-12-28 05:22:07 -0600

I am deploying openstack example architecture with two vm's on vmware esxi host.

All services keyston,glance,nova,neutron,horizon are working well but for deploying instance when i am creating a provider network subnet nova and neutron services stopes on compute node and when i am trying to restart them they are not starting.

Here i am describing my scenerio.

Management network - 134.119.x.y/29 Provider network - 134.119.a.b/29 Host vm 1 as controller node with one managment network ip. Host vm 2 as compute node with another management network ip.

Before adding all network and compute services was up and running very well.

But after adding provider ip subnet to provider network compute and network service goes down and wont starting again.

Here is status.

Compute (nova service) status. (compute , down)

[root@controller ~]# openstack compute service list
+----+------------------+-----------------------+----------+---------+-------+----------------------------+

Here is network service related information.

[root@controller ~]# openstack network list
+--------------------------------------+----------+--------------------------------------+
| ID                                   | Name     | Subnets                              |

+--------------------------------------+----------+--------------------------------------+

Network agent status.(False , up)

[root@controller ~]# openstack network agent list

+--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+

Due to this both nodes compute & controller respectively not communicating with each other nor pinging.

Please guide me about this error/issue.

Thanks.

see log file , carding logical relation about all nodes.

But before adding subnet to provider network every thing was fine .

I tried this 3 times every i add ip subnet to provider network nova and neutron goes down on compute node.

After subnet deletion all services become live again.

And during this restart service not working at all.

May be something required to do in networking part on vmware EXSi host server ?
