The "get()" utility function does have a checksum parameter. https://avocado-framework.readthedocs.io/en/67.0/api/utils/avocado.utils.html#avocado.utils.vmimage.get And caching is available both with or without a checksum option given. Now that you've mention this, for this use case, it's desirable to provide the checksum. > > I think we want to make this benign for people on a slow and/or > data-capped network connection.

So, I'm wondering if it sounds like a good idea to define some very rough ranges at this point: * quick: <= 0.5s * normal (doesn't have to exist as an explicit category, IMO) * slow: >= 30s But again, it's hard to come up even with the right times... unless we had a baseline environment that could be reused by all.

This acceptance test, validates that a full blown Linux guest can successfully boot in QEMU. In this specific case, the guest chosen is Fedora version 29. The method for checking the successful boot is based on "cloudinit" and its "phone home" feature. The guest is given an ISO image with the location of the phone home server, and the information to post (the instance ID). Upon receiving the correct information, from the guest, the test is considered to have PASSed. This test is currently limited to user mode networking only, and instructs the guest to connect to the "router" address that is hard coded in QEMU. To create the cloudinit ISO image that will be used to configure the guest, the pycdlib library is also required and has been added as requirement to the virtual environment created by "check-venv".
