I'm new to OpenStack and I'm learning how to create images for it.

There are two instructions in docs, describing how to create Ubuntu and CentOs images manually, using installation iso-files and some command line stuff.

I started with Ubuntu, dealing with 12.04.5, 14.04.2 and 14.10 iso-images. Generally, the instruction given in docs is worked, and I'm now able to run my self-made images in OpenStack, but no one of them print anything to OpenStack Instance Console Log.

I looked thru the CentOs image creation instruction, and there is "Configure console" section there - I guess that is the thing I missing for my Ubuntu images.

So, the question is: should I consider the situation, wheh there are no such section on Ubuntu image creation page, as documentation's bug (so I will submit it to launchpad), or I just did something wrong?

Try downloading an Ubuntu cloud image, upload to glance and see your getting same issue in console.

Why cloud image? Documentation mention iso, and I try to follow it.

I am trying debug your setup to see issue is with .iso or vnc console.

Sorry, my question probably was unclear. VNC is okay and console in OpenStack web dashboard works fine. What doesn't working is Instance Console Log. I edit the question.

Then it is not specific to Openstack but related to OS.

This occurs when the Compute service attempts to retrieve the log output of the instance via a serial console while the instance itself is not configured to send output to the console. To rectify this, append the following parameters to kernel arguments specified in the instance's boot loader:

console=tty0 console=ttyS0,115200n8

Thanks for answering, for understanding we would like to know this is specific to OS.

So, should it be considered as bug, while there are no such instruction at documentation page?
