I have some instance which I can't boot and they go in ERROR state. As I can't delete them from the dashboard or the nova CLI, I run the following mysql command

update instances set deleted=1 where vm_state='error' ;

After I run that command, when I run

nova list

or in the admin tab on the dashboard, I see that all my instances which where in ERROR state, are deleted.

But in the project tab, under the overview menu, I saw all my old instances. And so I fill up my quotas super fast.

Is there a way to update the dashboard so He fetch the good informations about my running instances ?
