Silvia, Sorry about that. I missed that. If you have installed devstack, then you can use the screen sessions for checking the logs. Following is a link which provides the different commands for accessing screen sessions and the short cuts to access it.

The day before I've created several times groups of 5/6 instances and than deleted. They were correctly launched (except for the allocation of the IP addresses in compute hosts that are not also controller, but I thinks this was a problem of the VTN configuration with OpenDayLight). 2015-06-22

Hi Abhishek, it seems there are some errors in the log you suggested to check. I've attached it as a G-drive link because it's too big. Thanks Silvia​ screen-n-cpu.log https://drive.google.com/file/d/0ByUj7Zpz-6NFR2NvVnJkOHE2Rm8/edit?usp=drive_web ​ 2015-06-22 10:49 GMT+02:00 Abhishek

Nova has different log files, one for the scheduler, one for the conductor, one for the api-server, and one for the compute agent. If you don't see anything at all regarding openstack in /var/log, is there a chance you've enabled syslog logging? If you're running from devstack, you might have

Hi all, I have 4 VMs in a server, managed by ESXi. One of these perform as OVS, one is the Openstack controller and the other two are the compute hosts. Yesterday I set up Openstack via devstack with Opendaylight integration for VTN. There was some issue in the VTN configuration but I was able to

I would check for errors in the nova compute logs. In some cases I had the same error, but the actual root cause was that the nova compute log was failing to setup networking for an instance. The request went back to the scheduler, which selected another compute node, but failed in the same way
