Hi, I am trying to migrate VMs hosted over vcenter to opennebula cluster using live migration, but getting following error message.Please suggest

* * *

**Opennebula 5.10 , vcenter 6.0 and esxi 6.0.**

**Integrated vcenter in Opennebula using sunstone -\> import VMs, network , datastores -\> perform live migration from sunstone console by selecting VM that need to be migrated. Getting below error message in GUI console log:**

Are you sure, that you aren’t using kvm driver for migration?  
Check your hosts vm- and tm\_mad

Are you trying to migrate from KVM hosts to ESXi hosts? If not check @slnt_opp says.

I believe it is using vcenter . I am not sure how to change it. check below snapshot template tab of VM confg from suntone.

Check host im and vm mad via onehost show, should be  
IM\_MAD=“vcenter”  
VM\_MAD=“vcenter”

And maybe datastore driver check would be useful too.
