I have been looking for a resource which explains the VM migration in details in Openstack. I found some good resources such as

http://bodenr.blogspot.com/2014/03/openstack-nova-vm-migration-live-and.html

and

https://www.openstack.org/summit/vanc...link text

However, they do not draw a holistic picture of whole migration process in Openstack. I would like to ask if anyone knows such a complete resource, please share it with others here. There are many resources which explain how to configure and run live migration, but I couldn't find something which explains e.g. the interaction between different Openstack services while migration is in progress.

Let's make this post a good place for those who are interested to know migration in depth.

Thanks
