Hi,

I'm trying to import a KVM VM into Ovirt.

First I tried the GUI VM import functionality and this failed with the error below. However other VMs from the same source host were imported fine.

This is a bug that was probably fixed in later versions.
 
Second I tried using the disk upload feature in the GUI, but this created the target disk then fails to upload the content - I've ensured that the relevant CAs are loaded into the browser.

You need to check that ovirt-imageio-proxy is running, and that
engine is configured correctly to access it.
 

Third I successfully imported the VM into an ovirt 4.2 instance in the lab, but can find no way of then importing it into ovirt 4.0 as the storage domain format seems not to be backwards compatible.

You can create a storage domain v3 in both 4.0 and 4.2, then you can
detach the storage and attach it to 4.0 system.
 
Finally I used the upload_disk.py example script from python SDK. This creates the disk and starts to upload the content but always fails at 2% with "socket.error: [Errno 32] Broken pipe"

Any ideas on how I can get this qcow2 image loaded into ovirt 4.0?

It should work, but many bugs were fixed since 4.0. Your best bet is to upgrade
to 4.2.
