No operating system was found. If you have an operating system installation disc, you can insert the disc into the system's CD-ROM drive and restart the virtual machine.Virtual machine <virtual machine name> was migrated from host <ESXi host>, <source datastore> in <cluster> to <ESXi host>, <destination datastore> in <cluster>vmware.log.VMware vCenter Server 8.x

There's another datastore in vCenter Server with the same naa id as either the source or destination datastore of storage vMotion.
Naa id is generated by storage and stands for network addressing authority identifier. This identifier is supposed to be unique globally even across storage systems.
vCenter Server would not prevent storage devices with the same naa id from being presented but this would lead to unintended side effects including virtual machine crash after storage vMotion to or from the storage device with duplicate naa id.
Storage vendor needs to be engaged in this situation to address and get rid of the duplicate naa id from storage system.
For more information on datastore naa id, please refer to Identifying disks when working with VMware ESXi.
To identify duplicate naa id in vCenter Server, one could login to vCenter Server ssh:
/opt/vmware/vpostgres/current/bin/psql -d VCDB -U postgresselect * from vpxv_ds_lun_info;
