Vcenter to opennebula migration

Community Support

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:

Expected results:

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

3

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.
