Hey folks! I'm starting a new thread for this to trim the

The Story So Far: there is a Fedora release criterion which requires
Fedora to boot on Xen:
"The release must boot successfully as Xen DomU with releases providing
a functional, supported Xen Dom0 and widely used cloud providers
We (QA group) had a discussion about removing this criterion entirely.
That has now morphed into the idea that we should tweak it to be
focused exclusively on the "widely used cloud providers utilizing
Xen"...by which we mean EC2. At the time this criterion was invented,
all EC2 instance types used Xen; now, some still use Xen, and some use
So it seems like this would also be a good opportunity to revisit and
nail down more specifically exactly what our cloud requirements are.
bcotton suggested that we require two sample instance types to be
tested, c5.large (KVM) and t3.large (Xen). (I've also mailed Thomas
Cameron, ex-of Red Hat, now of Amazon, for his opinion, as it seemed
like it might be worthwhile - he's promised to get back to me).
So, for now, let me propose this as a trial balloon: we rewrite the
above criterion to say:
"Release-blocking cloud disk images must be published to Amazon EC2 as
AMIs, and these must boot successfully and meet other relevant release
criteria on c5.large and t3.large instance types."
Sounds good to me if we trim it down to a few instance types that we think
will cover Xen and KVM based booting in EC2. For Fedora CoreOS we'll be doing
some automated testing in EC2. I don't know if we have a certain set of instance
types we'll be using for that, but the information that Matt provided should
help us decide.
