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 *qemu-nbd: Failed to blk_new_open '/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': Could not open '/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': Permission denied* Please suggest me if Ovirt has any API to open a disk from a storage domain and write data to it Regards Shafi On Wed, Mar 20, 2024 at 3:23 PM Nathanaël Blanchet <[email protected]> wrote: > Le mercredi 20 mars 2024 à 12:19 +0530, Shafi Mohammed a écrit : > > Hi Team , > Hi > > > > I am new to Ovirt and have been using KVM off late .
