It's worth noting that at least part of the justification for the criterion in the first place was that Amazon was using Xen for EC2, but that is no longer the case, most if not all EC2 instance types no longer use Xen.
I don't know where you got that particular piece of information. It isn't correct. Most EC2 instance types still use Xen. The vast majority of EC2 instances, by volume, are Xen.
Correct, it's only specific types of new hypervisors that use kvm based, plus new HW like aarch64.
That being said I don't believe testing we can boot on xen is actually useful these days for the AWS use case, it's likely different enough that the testing isn't useful, we'd be much better testing that cloud images actually work on AWS than testing if it boots on xen.
Yeah, that's where I was going to go next (there has already been a thread about this this morning). If what we care about is that Fedora boots on EC2, that's what we should have in the criteria, and what we should test.
IIRC, what we have right now is a somewhat vague setup where we just have 'local', 'ec2' and 'openstack' columns. The instructions for "Amazon Web Services" just say "Launch an instance with the AMI under test". So we could probably stand to tighten that up a bit, and define specific instance type(s) that we want to test/block on.
OK, so, to move forward with this (and looping in cloud list): does someone want to propose a set (ideally small - 2 would be great, one Xen and one non-Xen, if we can cover most common usages that way!) of EC2 instance types we should test on? With that, we could tweak the criteria a bit to specify those instance types, tweak the Cloud validation page a bit, and then drop the Xen criterion and test case.
Thanks everyone!
