That question mark is what's being returned by the Nova API, so the bug is on Nova's end. I suspect it may be either the particular type of instance/image you're using or a configuration error.

I don't see how closing this bug improves the situation. If it's a Nova bug, lets move it to Nova. If we need more logs, ask and we'll deliver them. Can you specify which Nova API is used to get this and we'll see if we can reproduce this issue via the API?

I *did* add Nova to the bug report.

This actually looks like an issue with your image. Something in the guest appears to be writing '?' (or maybe a random unicode character) to the serial console.

The cli version of the command is:

nova console-log <instance_uuid>

If it is also producing a ? then I suspect that it is actually your image doing this.

It seems like it does returned from nova api:

# nova console-log 101c48cc-9f8f-4ad1-ae78-a56ce008f2dc
?

I'm not sure if it comes from the image, I tried other images (Fedora 17 for example) and the instance log was blank.
