Hi,
I want to copy a volume from one to pool to another pool through libvirt golang api but
I’m unaware of any such functions. Can anybody guide me a little bit here?
Best Regards,

The "StorageVol" interface in Go provides "Upload" and
"Download" methods
that associate a "Stream" with the volumes.
So you'd call Download on the original vol, Upload on the target vol, and
read from one stream, and write to the other stream.
Regards,
Daniel

If two pools on the same nore I'm recommend to use createvolfromxml. In
this case libvirt do internal copy on the node via qemu-img.
Download/upload takes all data on node that runs client.
