The libvirt image cache manager wants to verify that the images it is managing have not become corrupt. We therefore write checksums for these images to disk and verify them as part of the cache management periodic task. This checksumming was originally done as part of the setup for a new virtual machine. This has been refactored so that generating a checksum on a large file will not delay the startup of a VM. Note that these checksums are intended for detecting corruption, not malicious system admins. Change-Id: I781877b342207cb2cf03eb48bd89456846cbf487

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
