Hello,

I was running Ubuntu 13.04 and upgraded tonight to 13.10.  I was running the
Ubuntu Precise 1:2013.1.3-0ubuntu1.1 on 13.04 and am now on 13.10's provided
1:2013.2~rc2-0ubuntu1.

After getting the box up, migrating the nova database failed with the below
error.  I am using MySQL.

Suggestions on how to fix this?

Thanks,
Blair
