Thanks Mathieu! We've discussed further on IRC, but summarising below
for the list.

I contacted Binary Lane's support and they advised that while they
didn't support QCOW2, I could resolve the resizing issue by using their
"BYO OS" configuration, rather than their built-in image configurations
like "Debian". Doing so disables their auto-magic storage resizing
feature which seems to choke on the multi-partition image. I can live
with uploading a 1.5GB raw image and then resizing the partition. :)

Noting that you also have a working demo of a single partition image
type, that we may see in the near future.

Thanks very much for your help!

Regards,
Ben
