<div>> Today when I test instance live migration in</div>
<div>> CLI (nova live-migration --block-migrate</div>
<div>> 0b30368a-2eaf-42e5-918a-f855bad91f63 Compute02) ,I encounterd the following error massages:</div>
<div>></div>
<div>> But when I use dashboard</div>
<div>> to migrate the vm,it appears to success.I'm using Havana version. </div>
<div>></div>
<div>> My Compute nodes' CPU are :</div>
<div>> Compute01:Intel(R) Xeon(R) CPU E5405 @ 2.00GHz *2</div>
<div>> Compute02:Intel(R) Xeon(R) CPU E5335 @ 2.00GHz *2</div>
<div> </div>
<div> </div>
<div>Walter,</div>
<div> </div>
<div>I know there are quite a few different code-paths for semi-similar functionality :(</div>
<div>As far as I know using the dashboard will not issue a block migration.</div>
<div>I *guess* it will do a non-live migration if there is no shared storage.</div>
<div> </div>
<div>Concerning the CPU issues:</div>
<div>https://bugs.launchpad.net/nova/+bug/1082414</div>
<div> </div>
<div>For live migrations without shared storage there is also this bug to take in account:</div>
<div>https://bugs.launchpad.net/nova/+bug/1270825</div>
<div> </div>
<div>I'm not sure what the state of migrations is in Icehouse.</div>
<div>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.</div>
<div> </div>
<div>Seems like there is still some room for improvement here...</div>
<div> </div>
<div>Cheers,</div>
