Partially addresses bug #1045152 On a heavily loaded compute node, it can be observed that periodic tasks take so long to run that the report_state() looping call can be blocked from running long enough that the scheduler thinks the host is dead. Reduce the chance of this happening by yielding to another greenthread after each periodic task has completed and each loop in some methods that has linear relationship with the number of instances.

The Choose Your Own Adventure README for Nova
You have come across a cloud computing fabric controller. It has identified itself as "Nova." It is apparent that it maintains compatibility with the popular Amazon EC2 and S3 APIs.
To monitor it from a distance: follow @openstack on twitter.
To tame it for use in your own cloud: read http://docs.openstack.org
To study its anatomy: read http://nova.openstack.org
To dissect it in detail: visit http://github.com/openstack/nova
To taunt it with its weaknesses: use http://bugs.launchpad.net/nova
To watch it: http://jenkins.openstack.org
To hack at it: read HACKING
To cry over its pylint problems: http://jenkins.openstack.org/job/nova-pylint/violations
