Comment 2 Brent Eagles 2013-02-14 18:33:12 EST
After several attempts, I have been unable to reproduce this issue. Are there other variables not listed here? For example:

* Multiple compute nodes
* Multiple network nodes
* Nested VMs (compute, network, etc running in VMs)
Comment 3 Ofer Blaut 2013-02-15 03:53:58 EST
I was using two compute nodes .
one of the compute nodes act as nova network & compute node, the other doesn't have nova network.
no Netsted VMs
Comment 4 Brent Eagles 2013-02-26 13:58:24 EST
I was unable to reproduce using a configuration similar to the one described. If it is easy to reproduce or recurs, please provide the following information:

- nova.conf files for both compute nodes
- compute and network log files for the relevant period (e.g in your attachment, the first entry is 10:48:36 and the second is 11:17:52)
- the output of nova show 'instance id' for each of the instances

If it recurs, would it be possible to get access to the system? 

Comment 5 Ofer Blaut 2013-02-27 03:39:09 EST
Issue is not reproduced on build openstack-nova-network-2012.2.3-1.el6ost.noarch
