[impact]

creation of qemu imgs for use with autopkgtest-virt-qemu is done with the autopkgtest-buildvm-ubuntu-cloud program. This was dropped in version 5.6:

however, precise and trusty are not 'obsolete Ubuntu release names' just yet.

[test case]

run autopkgtest-buildvm-ubuntu-cloud with either -r precise or -r trusty:

$ autopkgtest-buildvm-ubuntu-cloud -r trusty
Downloading https://cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64.img...

No image exists for this release/architecture
$ autopkgtest-buildvm-ubuntu-cloud -r precise
Downloading https://cloud-images.ubuntu.com/precise/current/precise-server-cloudimg-amd64.img...

No image exists for this release/architecture

[regression potential]

very little, as this is a simple change and using precise or trusty with the script does not work at all currrently. any regression would be around downloading the ubuntu-cloud image.
