I might have some more details, but I don't know what it means.
When I do 'qemu-img info' on the VM image in backup I get:
file format: raw
virtual size: 128 GiB (137438953472 bytes)
disk size: 128 GiB
When I do the same on the VM image that was copied to the new storage I get:
file format: raw
virtual size: 128 GiB (137438953472 bytes)
disk size: 4 KiB
Am I reading this wrong, or did something go wrong in the import ?
