VM instance can not be deleted by nova

[chenhaiq]

When I run cmd:
nova delete 98106004-feca-419f-8781-ec79333032d6

There is an exception in n-cpu process:

I can delete the instance after restart n-cpu process.

Not sure when that fix would be merged in master, since I not find work-around to delete the instance, (db delete is not workround)
