Open Stack

hi:Robert     Thank you for your reply.
     About the CPU issue,I have switched my Comoute02's CPUs to Intel(R) Xeon(R) CPU E5405 @ 2.00GHz *2, and now it works.     
cheers!

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...
 
Cheers,
Robert van Leeuwen
