> Steps to reproduce :
> 1. Have at least one advanced zone with KVM cluster (2 kvm hosts)
> 2. Make sure that the setup has at least 2 zone wide primary storages. (f=
rom ex: zwps1, zwps2)
> 3. Deploy a VM as admin
> 4. Create a datadisk of size 5 GB as admin on zwps1
> 5. attach the above datadisk to the VM in step 3
> 6. detach the data disk
> 7. initiate migrateVolume command for the above datadisk to zwps2
> Observations:
> (i) Found the following NPE in mgmt server logs
