[tjdett]

It appears #1917 is back in QEMU:

Thanks for the report @tjdett - I'll take a look...

Hi @tjdett I believe this is because we have not merged #3475 yet... I reproduced the issue, and then took the current HEAD, merged that PR in and re-tried and the test worked (apart from I had to use the ubuntu image, as for some reason I could not download and convert debian:8 to an ACI...)

3475 is pending the status of patches being pushed towards/merged to upstream QEMU - and I've just chased that to see if we have some progress there and hopefully get that PR merged.
