If it could be helpful I noticed that I have this error when I restart the ODL controller. 2015-06-22 12:11 GMT+02:00 Abhishek Shrivastava : > Yes, and because of that problem only the new Instances are not been > created. > > On Mon, Jun 22, 2015 at 3:39 PM, Silvia Fichera > wrote: > >> The da

Yes, and because of that problem only the new Instances are not been created. On Mon, Jun 22, 2015 at 3:39 PM, Silvia Fichera wrote: > 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 > address

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 12:

On the 19th in the morning I've done several trial, after 9.30 a.m. I don't remember exactly when. The day before (when I've installed it) everything was working fine. 2015-06-22 11:49 GMT+02:00 Abhishek Shrivastava : > Hi Silvia, > > One more thing, can you please tell me the exact time when you

Hi Silvia, One more thing, can you please tell me the exact time when you have created the Instance. On Mon, Jun 22, 2015 at 3:07 PM, Silvia Fichera wrote: > 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 bi

According to this, the Instance creation failed because the Neutron was not able to "create_port_postcommit" so you have to check the why it is happening, as I have no idea on how Neutron works. Also can you tell me how many Instances you have created before this error happened. On Mon, Jun 22, 2

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 ​ 2015-06-22 10:49 GMT+02:00 Abhishek Shrivas

Hi Silvia, Look for logs in screen folder and specifically screen-n-cpu.log, or you just upload the same file, will tell you accordingly the cause of error. On Mon, Jun 22, 2015 at 2:15 PM, Jamal Arif wrote: > Silvia, > > Sorry about that. I missed that. > > If you have installed devstack, then

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. http://www.rushiagr.com/blog/2013/06/05/li

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 logs

Hi Jamal, as I already told previously I don't have nor nova nor neutron in /var/log because I have Installed openstack using devstack. I will look for errors in /opt/stack/logs and, if I find somthing I will post it. Thanks 2015-06-22 10:16 GMT+02:00 Jamal Arif : > ​You can check in two places.

​You can check in two places. - On Controller: Check for neutron server logs in /var/log/neutron/​ Check for Nova schedular etc in /var/log/nova/ - On Compute Hosts: Check for Nova Compute logs in /var/log/nova/nova-compute.log There can be multiple reasons for this error starting

Good morning. As I told I can't find the folder /var/log/nova. So which log should I check? Thanks 2015-06-19 16:23 GMT+02:00 Salvatore Orlando : > 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

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 wh

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 c
