I know this is going to sound harsh, but you should not be extending 
Nova's database in any way outside of submissions to the upstream Nova 
codebase.

What it sounds like you want to do is to publish network statistics 
(bandwidth/IO in and out of VMs) about your instances. If that is 
correct, you should probably look to the Ceilometer project to meet your 
needs.
