There isn't really any block migration specific configuration. So long as your multi-node nova installation is working you should be fine.



The source and target nodes must have compatible CPU architectures and capabilities. Nova-compute on the target node will need access to the VM’s base image (i.e. on Glance if that’s what you’re using) so that it can fetch it during the migration.



The command to do the migration is,



$ nova-manage vm block_migration <ec2 instance id> <destination node>
