<br>
I have problem with live migration and block migration with IBM SVC plugin for Cinder at Fibre Channel. I have instance (boot from volume) running at compute node ch1nod2 and I am trying to migrate on second compute ch1nod3. I run the command and it takes about
1 second, after that instance is in state MIGRATION and at ch1nod3 I can see a new paused instance. It takes about 6 minutes and after I can see the errors bellow.<br>
