Open Stack

Unsure if you got this fixed or not.

But the errors that you have in your paste’s indicate that your amqp, looks like qpid in this case, is not available to your services.  I would restart qpid, then restart all the other openstack services and verify they can successfully connect.  We run rabbitmq for amqp – so I can’t provide anymore help with qpid.

Subject: [Openstack-operators] VM Can't get DHCP IP

Hello,
I'm running OpenStack RDO with the following setup.

- 1x Controller Node ( Neutron - Nova -   glance - Horizon - Keystone - GRE +   FlatDHCPManager)
-  10x Compute Nodes ( Nova Compute  - KVM )
- OS : CentOS 6 - 64bit

Suddenly all vm's on the compute nodes can't get new IP address from the controller node. It was working properly hours ago without any modifications from me. This log from the controller node - **many errors**
 http://paste.openstack.org/show/88016/

And this from the compute node
 http://paste.openstack.org/show/88017/

# rpm -qa | grep -i openstack
