Walter, I know there are quite a few different code-paths for semi-similar functionality :( As far as I know using the dashboard will not issue a block migration. I *guess* it will do a non-live migration if there is no shared storage. Concerning the CPU issues: https://bugs.launchpad.net/nova/+bug/1082414 For live migrations without shared storage there is also this bug to take in account: https://bugs.launchpad.net/nova/+bug/1270825 I'm not sure what the state of migrations is in Icehouse. There were talks to move the migration tasks to the conductor/schedule(?) in the codebase but I haven't read anything in the release notes about this. Seems like there is still some room for improvement here...
