On further investigation, the "No such file or directory" error occurs
when using snapshot=on.

ie:

This fails:

./x86_64-softmmu/qemu-system-x86_64 -drive 
'file=http://127.0.0.1/~rjones/cirros-0.3.1-x86_64-disk.img,if=virtio,snapshot=on'

This works:

./x86_64-softmmu/qemu-system-x86_64 -drive 
'file=http://127.0.0.1/~rjones/cirros-0.3.1-x86_64-disk.img,if=virtio,readonly=on'

Also, creating a qcow2 file which has the http://... path as its
backing file also works (which should have the same effect as
snapshot=on, but I understand the implementation is a bit different).

Rich.
