Hi,
My qemu runs on a 3rd party distributed block storage, and the disk backend protocol is nbd.
I notices that there are differences between default qcow2 local disk and my nbd disk, in terms of resizing the disk on the fly.
Local qcow2 disk could work no matter using qemu-img resize or qemu monitor 'block_resize', but the nbd disk seemed to fail to detect the backend size change(had resized the disk on EBS at first). It said "this feature or command is not currently supported".
Is that possible to hack qemu nbd code, making it the same way as resizing local qcow2 disk? I have the interface to resize EBS disk at backend.
Regards,
Bob
