Hi Guys ,

I am writing a tool to migrate VMs from KVM to Ovirt .

I created a storage domain and tried to expose it to NBD server to write the data from the source Vm disk . But im facing a nbd permission issue . Even a copy or write is restricted .

Actual Command qemu-nbd -f qcow2 /rhev/data-center/mnt/192.168.108.27: _storage/d62b04f8-973f-4168-9e69-1f334a4968b6/images/cd6b9fc4-ef8a-4f40-ac8d-f18d355223d0/d2a57e6f-029e-46cc-85f8-ce151d027dcb

just out of curiosity, did you look at the built-in functionality of importing VMs from KVM via Libvirt? https://www.ovirt.org/develop/release-management/features/virt/KvmToOvirt.ht...
