Nova folks,

I have some concerns about the approach adopted in the trusted computing 
blueprint 

https://blueprints.launchpad.net/nova/+spec/trusted-computing-pools
http://wiki.openstack.org/TrustedComputingPools

Basically, the assumption of this blueprint is that Nova has to be responsible 
for caching the "trust" status of hosts. In order to do this without allowing 
hosts to lie to the scheduler, a long lived component must be created. My sense 
is that this approach is too invasive and inappropriately pushes 
responsibilities from the "trust" infrastructure into Nova.

I have been working with Fred Yang to try to address these concerns--and I'm 
confident that Nova can adjust in a reasonable way to accommodate trusted 
computing. However, the blueprint appears to have been approved with the 
approach I don't like baked in, and I don't want to overstep.

So I ask: Is there a consensus among nova-core that the approach given in the 
blueprint needs to be changed? Or the other way around, is there a consensus 
approving of this approach?

Thanks
