If migration is needed then first they will be migrated to appropriate cluster before attaching. commit 64153a43711420224655bfbe248b4b87474a1f23 Author: Anshul Gangwar <anshul.gang...@citrix.com> Date: Fri Jun 20 14:32:05 2014 +0530 CLOUDSTACK-6830: Fixed [hyper-v] during VM migration, volumes on zone wide primary store requires storage migration resulting in failure of VM migration. This also improves the hostsformigration api. Firstly we were trying to list all hosts and then finding suitable storage pools for all volumes and then we were checking whether vm migration requires storage migration to that host. Now the process is updated. We are checking for only those volumes which are not in zone wide primary store. We are verifying by comparing volumes->poolid->clusterid to host clusterid. If it uses local or clusterids are different then verifying whether host has suitable storage pools for the volume of the vm to be migrated too. Thanks, Anshul
