Thanks for stepping in. Of course we always want as much stuff as
possible to work, but that does not mean we block the release on it. We
certainly want Fedora to work as a guest on VMWare, VirtualBox and
Parallels too; we don't block the release on any of those either...

b) you can use fedmsg / fedora-messaging:
A message is emitted every time a compose attempt finishes (on the fedmsg
topic 'org.fedoraproject.prod.pungi.compose.status.change': see
for a log of past messages). What you will want to do is listen for
completed Branched and Rawhide composes and run tests whenever one
completes successfully. This is already exactly what we do to schedule
openQA tests; you can crib from the openQA test scheduler:
particularly the fedmsg consumer:
c) ideally it would be good to report to both resultsdb and to the
wiki. Again, we already do this for openQA, and you can crib from the
reporting to ResultsDB might be tricky due to authentication issues,
I'm not sure if we ever put the openID auth stuff into production. For
wiki reporting you will either have to auth manually every so often or
ask Fedora infra for a special token that doesn't expire (this is what
we do for the openQA results).
Reporting to ResultsDB you do through resultsdb_api -
https://pagure.io/taskotron/resultsdb_api - and optionally you can use
my resultsdb_conventions -
https://pagure.io/taskotron/resultsdb_conventions - which makes it
somewhat easier (IMO anyway) and will make your results consistent with
those from openQA and Autocloud. Reporting to the wiki you can do
through my crazy python-wikitcms library -
https://pagure.io/fedora-qa/python-wikitcms . Again, fedora_openqa does
all this for openQA results, so you can crib from that. Let me know if
you have trouble with this.

It would be nice if you could ensure someone from Xen is actually
watching the Fedora lists, if working in Fedora is a target for Xen. We
*could* try and CC stuff all the time, but imagine if we tried to do
that for everybody. But yes, for future conversations of this nature
I'll try and remember to include those lists.

In theory, yeah, but given the history here I'm somewhat sceptical. I'd
also say we still haven't really got a convincing case for why we
should continue to block the release (at least in theory) on Fedora
working in Xen when we don't block on any other virt stack apart from
our 'official' one, and we don't block on all sorts of other stuff we'd
"like to have working" either. Regardless of the testing issues, I'd
like to see that too if we're going to keep blocking on Xen...
