Hi Guys ,
Thanks for the Info .
I am trying to migrate my data from local to Storage domain . But it
requires twice the effort in terms of space and time to copy the data to
the local file system and then upload the disk to it .
I created a storage domain and tried to expose it to the NBD server to
write the data from the source Vm disk . But I'm facing an 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

Please suggest me if Ovirt has any API to open a disk from a
storage domain and write data to it
You are trying to reinvent ovirt-img. Try it:
